RedHat exercises the GNU freedom by selling for money a distribution consisting mostly of free programs made by others.

For the record, RedHat is selling support for a distribution they have engineered. They aren't selling the distribution, except possibly a "media charge", year 1 to obtain the support and year 2 to maintain the support are the same price.

CentOS does not offer any support beyond the standard Open Source model of chat boards, bugzilla, etc. As a general rule, when I introduce Linux to a company with a small unsupported project, I bring in CentOS, not Fedora, because I know if it takes off we'll be bringing in RHEL 9 times out of 10 when the company decides they want/need support.

What happened to 'upstream upstream upstream'? by jdogalt · 2011-03-04 09:03 · Score: 1

Coincidentally enough, this state of affairs has been in place for 6 months, but this slashdot/lwn note comes the morning after I discovered the fact myself while trying (still as yet unsuccessfully) to rebuild the kernel with support for one odd driver enabled instead of disabled.

What strikes me as missing from the current set of comments, is how this move by RH seems at odds with their laudable history of 'upstream upstream upstream'. I.e., it seems to me that each of those hundred(s) of patches will now be significantly less likely to be adopted upstream, because of the added complexity of not knowing the details of - the mother of all deployments - of those patches. Details meaning, what other changes does it depend on, and happen to be shipped with in its stable and vast commercial deployment.

The other tinfoil-hat/security consideration is- if RH is as in bed with the NSA/CIA as it seems to me to have been for a very long time, and if the NSA/CIA did want to hide backdoors or backdoor enabling faults in the kernel, this is precisely the kind of move that would make those sorts of things orders of magnitudes more difficult for the traditional 'many eyes' effect to detect.

But of course, the bottom line is that what they are doing is quite legal, and from traditional business perspectives, quite ethical, and probably practical as well. But to the commenter who said there are 'no downsides' to this- No, there are downsides.

F5 Networks scratches off the serial numbers of Red Hat enterprise and produces CentOS so that they don't have to license Enterprise from Red Hat. They started this (CentOS) because every one of their Big-IP boxes was running Red Hat and they needed a stripped version to avoid paying the license fees for Red Hat's work. They explained this to me and then gave me the in-house extension to call if I found any Red Hat branding back when I worked there. (Yes, I have first-hand knowledge of these facts.) It's wrong at a moral level, but so what.

Most people who get Red Hat kernels end up applying all the patches anyway. Why is it more efficient or reasonable to release the kernel to all those people as straight-source plus patches, when they all want patched source in the first place. From an efficiency standpoint releasing the patches source is good for everybody but the leaches.

If F5/CentOS was going through the trouble to bundle and test all the packages form the same sources as Red Hat is getting them, then this wouldn't be a issue. It isn't about the sources of the sources, its about the testing and integration that Red Hat does that F5/CentOS has chosen to use with less than a nod.

So F5 is too cheap to pay for Red Hat's work, and they are too cheap to _duplicate_ Red Hat's work, and they are too cheap to build a distribution that _only_ contained what they actually needed, so where _exactly_ is Red Hat wrong for the very human response of saying "blow off, you freeloaders..."?

Besides, I bet if you pay support, or ask nice, you can get the patches anyway. The fact that the default distribution is fully patched instead of making you spend the time to patch it yourself is actually a _win_ for the paying customers.

And all of these actions from both companies are fully GPL compliant.

So where is the "problem" really?

Why is it so hard for FOSSies to understand that everything has a cost and the tragedy of the commons is all too real?
For all the FOSSies out there, it is just simple math. Red Hat uses the money they get from RHEL to make Linux a better OS by providing developers to the community, fixing bugs, and providing much needed R&D. Do you think the shit jobs will get done if nobody pays for them? The more leeches like CentOS you have that take what others create while giving nothing in return the less the ENTIRE community has because RH loses money they would have otherwise gotten, which leads to less employees, which leads to less code for you to enjoy.

Bug fixing, QA, regression testing, nobody LIKES these jobs but they simply have to be done, except by and large in the FOSS model they don't.
The ONLY reason FOSS has gotten as far as it has on the server is companies paying millions to make it happen, full stop. Look at any LOC count and you'll see RH nearly always number one or two. What happens when fewer and fewer people pay? It is simple math, less money for R&D, less money for QA and regression testing, less money for developers and less code for the community as a whole it is a classic tragedy of the commons case.
Look at how many major FOSS companies have been bought out or are barely alive, if the FOSS model worked, why is this so? It is because the FOSS model was born in a time of abundance and now that we are in another depression the well is running dry. More and more free riders and less and less paying customers and what do you get? Less for all.
Seriously is it any wonder so few companies want to offer a native FOSS version of their programs? The "free as in beer!" brigade grows ever larger while simultaneously the amount of paying customers stagnates or even falls. It is simple math folks, the less RH gets the less it can share, period. In any other model the developers have legal repercussions that can at least keep free riders to a manageable level, not so in FOSS. That is why I believe as the economy grows ever more sour so too will the free riders simply cause too much drain on FOSS and cause it to fall behind while companies like Apple and MSFT are able to make gains and get farther and farther ahead. It is just simple math and all the shouts of "free as in beer!" won't change the figures.
