GPLv2 Vs. GPLv3

chessweb writes "Here is a rather enlightening article by Richard Stallman on the reasons for moving to GPLv3 that puts the previous TiVo post into the right context." From the article: "One major danger that GPLv3 will block is tivoization. Tivoization means computers (called 'appliances') contain GPL-covered software that you can't change, because the appliance shuts down if it detects modified software... The manufacturers of these computers take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv3 ensures you are free to remove the handcuffs. It doesn't forbid DRM, or any kind of feature. It places no limits on the substantive functionality you can add to a program, or remove from it. Rather, it makes sure that you are just as free to remove nasty features as the distributor of your copy was to add them."

    One rule for Tivo and another rule for IBM?

    Why should I have less right to install modified code on my mainframe than on the box under my TV?

    For all Stallman's huffing and puffing about defending freedom, it sounds like he caved in to big business here.

      Aaah, nevermind. Found it myself after searching through Stallman's dogma a bit more carefully.

      The ban on tivoization applies to any product whose use by consumers, even occasionally, is to be expected. GPLv3 tolerates tivoization only for products that are almost exclusively meant for businesses and organizations. (The latest draft of GPLv3 states this criterion explicitly.)

      The interesting part of it is that if you can reliably control what is run on the hardware, the costs can be transferred from the buyer/user of the hardware to others. This means the hardware can potentailly be sold at a lower price than more open hardware, allowing it to gain a competitive advantage if the reduction in functionality is smaller, in monetary terms, than the reduction in the price. If this is the case, both the buyer and the seller can also be said to be better off.

    On Services... (yeah, what -did- happen to that SAP bit?)
    One major danger that GPLv3.1 will block is Googlization. Googlization means services contain GPL-covered software that you can't change, because the product is never published and so no source code has to be provided. The manufacturers of these services take advantage of the freedom that free software provides, but they don't let you do likewise. GPLv3.1 new services clause ensures you are free to remove the handcuffs.

    On network-enabled devices...
    One major danger that GPLv3.2 will block is Xboxization. Xboxization means devices contain GPL-covered software that connect to a network that you can't change, because the network shuts you out if it detects modified software... The manufacturers of these devices take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv3.2's new network clause ensures you are free to remove the handcuffs.

    On ATI/nVidia Linux drivers..
    One major danger that GPLv3.3 will block is BLOBization. BLOBization means software packages containing GPL-covered software that communicate to a non-GPL-covered piece of binary software (BLOB) that you can't change, because the BLOB is not covered by the GPL... The developers of these BLOBs take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv3.3's new network clause ensures you are free to remove the handcuffs.

    On not having to GPL programs compiled using GCC..
    One major danger that GPLv4 will block is GPL-less compiling. GPL-less compiling means programs created using GPL-covered software that you can't change, because the actual program contains no GPL-covered source code. The developers of these programs take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv4's derivative work clause ensures you are free to remove the handcuffs.

    On using e.g. The Gimp to create your graphics..
    One major danger that GPLv4.1 will block is artization. artization means original works of art created using GPL-covered software that you can't change, because the work is strictly non-GPL. The artists of these works take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv4.1's new GPL-created works clause ensures you are free to remove the handcuffs.

    On working around the GPL by re-implementing (much the same that free software developers re-implement things covered by patents)..
    One major danger that GPLv4.2 will block is reimplementation. reimplementation means software programs developed based on, but re-implemented in a different way of, GPL software that you can't change, because the work is not GPL. The developers of these programs take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv4.2's new GPL-reimplementation clause ensures you are free to remove the handcuffs.

    On using GPL software internally only...
    One major danger that GPLv5 will block is in-houseation. in-houseation means software programs based on, developed with, and so forth and so on as set forth in the other clauses, that is only used in-house that you can't change because the source code need not have been made available. The developers of these programs take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv5's new out-house clause ensures you are free to remove the handcuffs. ...

    And so forth and so on. It should be pretty clear that the GPL is all about freedom - pure and utter total freedom to do as you wish without restriction, as long as the product of this doing is available to everybody else to do with as they wish without restriction as well. Whether this is truly freedom or not (i.e. as opposed to the BSD-style licenses) is a never-ending debate.

    Right, so let's say your local comic shop wants to buy an automatic transaction system for its inventory. Now there's lots of closed source alternatives out there, but being a geek they want to support open source and perhaps modify it themselves and release their source code. They look for some free software versions and the only one they find is a system that comes with preinstalled on the hardware (which is pretty good because their current hardware needs replacement) and so they go to buy it, before they realize that they won't be able to modify it, because its been tivoized. If this geek were buying it for his home he would have protections from this tivoization under the GPL, but because its for his comic shop, he has no such protections. This is good, why?

  6. GPL 2 & 3 and coupons by anwyn · · Score: 5, Interesting
    Suppose that Darth wants to do something bad with some Free software. The GPL prevents Darth from doing this, when it works, by a two step process.
    1. Darth realizes that he is doing something that requires a license under applicable copyright law. The GPL is the only license available.
    2. The provisions of the GPL do not allow what Darth wants to do, so that Darth can not use GPL as a license if he does it.

    Suppose that Darth goes ahead and does it anyway, what does the enforcement process look like? Darth gets sued under copyright law, like IBM did against SCO with IBM's counter claims. The free software side has to prove two things:

    1. Darth has done something that requires a license under applicable copyright law.
    2. The GPL does not protect Darth because Darth has not abided by its terms.

    In order the suit to be successfull against Darth, both steps have to succeed. Step (2) can be optimized by the FSF, by adjusting the terms of the GPL, to make it as difficult as possible for Darth. The GPLv3 is an improvement in this process. Step (1) is the step that the FSF can not control, because the applicable copyright law is written by the legislature (in the U.S. that would be congress), not by the FSF! Therefore, step (1) is the weak point! If Microsoft is ever sued under the copyright law because of the coupons, Microsoft will attack the week point of the argument (1). This is what Microsoft's lawyers will say:

    Microsoft has not and will not agree with any version of the GPL. Distributing these coupons does not require a license under applicable copyright law. Distributing coupons is not distributing software in the meaning of copyright law. Therefore the terms of the GPL (both versions) are irrelevant. The expiration date of the coupons is irrelevant. Game over.

    The key assertion in the above is:

    Distributing coupons is not distributing software in the meaning of copyright law.

    If Microsoft can win on the key assertion. Then it will win. If the lawyers for the free software side can knock out the key assertion then they will win.

    Why do the coupons exist in the first place? Why did not Microsoft just hand out SuSE installation DVDs? The reason is obvious. Microsoft did not want to become a GNU/Linux distributor. The coupons are a dodge to get around this. The whole raison d'etre for the coupons was that that Microsoft avoid becoming a GNU/Linux distributor! Can anyone believe that Microsoft allowed the coupon scheme to proceed, without first getting on Lexis and finding out whether the scheme would work? It is guaranteed that in some Microsoft lawyer's briefcase, there is a brief. And that brief deleniates in excruciating detail why the coupon scheme does not make Microsoft a GNU/Linux distributor. And the brief was checked and rechecked by multiple lawyers before the coupon scheme was ever allowed to proceed.

    The free software argument against the MS-Novel coupon scheme, is a chain. And like any chain, it is only as strong as its weakest link. It is no good for free software advocates to sit back and congratulate themselves on how strong their strong point (2) is. Of course it is strong! The FSF deliberately designed the GPLv3 to make it strong! The point is, that Microsoft is not going to attack this strong point. Microsoft is going to attack the weak point (1).

    Instead of congratulating them selves, free software advocates should be critically examining their own arguments looking for weak points. And when they find one, they should research the caselaw looking for ways to shore up their arguments! They should not be replying to the weak points with mere repeated assertion of what they hope should be true, instead they should do some real scholarship.

    It's kind of insane to think that this will stop anything. The PS3 runs Linux (a generic PPC Linux no less) with no problems at all. It sure as hell does not mean you can access the proprietary portions of the PS3 that Sony don't want you to see. Why? Because Linux is running over a virtualized set of hardware. I'm sure if push came to shove that Tivo would do exactly the same thing, ensuring whatever code or functionality they wished to hide stayed hidden.
