EFF Warns TI Not To Harass Calculator Hobbyists
Ponca City, We love you writes "The EFF has warned Texas Instruments not to pursue legal threats against calculator hobbyists who perform modifications to the company's programmable graphing calculators. TI's calculators perform a 'signature check' that allows only approved operating systems to be loaded, but researchers have reverse-engineered signing keys, allowing tinkerers to install custom operating systems and unlock new functionality in the calculators' hardware. In response, TI has unleashed a torrent of demand letters claiming that the anti-circumvention provisions of the Digital Millennium Copyright Act require the hobbyists to take down commentary about and links to the keys. 'This is not about copyright infringement. This is about running your own software on your own device — a calculator you legally bought,' says EFF Civil Liberties Director Jennifer Granick. 'Yet TI still issued empty legal threats in an attempt to shut down discussion of this legitimate tinkering. Hobbyists are taking their own tools and making them better, in the best tradition of American innovation.'"
someone show apple this news. :/
What about all the similar crap that goes on with other devices? iPhone, XBOX, Wii, NDS, plus loads others?! EFF, why aren't you defending user's rights there?
The product was not sold as a computer or development platform. It was sold as an end user product with documented functionality as described in the user's manual. Sure enough, when the hacks disable their machines TI will get the support call. Most slashdotters will probably flame me for this.
I would be very surprised if a calculator hobbyist tried to get support for a modded device. And it is pretty easy for TI to say the warranty is void so STFU in that situation.

It's really hard for me to see how TI has a case under the DMCA at all. They're claiming the anti-circumvention clause, but it doesn't seem to apply here.
The anti-circumvention clause makes it a violation to circumvent copy protection -- but what the hobbyists are circumventing in not copy protection, it's a validation key. Without the key, you can still read and copy the existing OS without a hitch. The key is needed to put you own intellectual property on the device, no to copy theirs.
The key itself was never published by TI, and as far as I can tell was never registered with the copyright office, so copyright doesn't apply to that (even if it can apply to a number, which I doubt.)
So where's the copyright violation? this looks like a criminal (bad faith) abuse of the DMCA to me.
No. The DMCA reads "No person shall circumvent a technological measure that effectively controls access to a work protected under this title".
How does TI's signing system do that? The TI system just prevents people from loading a new OS onto devices that they already own. It doesn't protect access to work.
The DMCA is a bad law, but it's not so broad as to say "everything to which a technology company with a market capitalization of over $10 million objects is henceforth illegal."
When will companies realize that kicking and screaming about an issue they can't legitimatize will kick them in the testicles? Will T.I. really lose oodles of greenbacks because Joe geek likes to mod his calculator to play Mario or run Linux or watch porn (last item questionable). I highly doubt people hacking their calculators will cut into revenue, if anything it will increase it by bolstering interest in the extended possibilities of their products.
Technophiles do not like to buy equipment they are legally castrated for modding or learning about the inner-workings.
When profit is valued more than satisfaction of customers...oh wait..*status quo* *status quo*.
The answer to the original question lies our government and legal system's ability to cease giving them the fucking pacifier every time they cry wolf.

I have an automotive screwdriver that was sold as an automotive screwdriver, not a...a... window...keeper-open...thing.
If Sears/Craftsman has a problem with that, tough. Same concept.
That's why those types of things are done with fuses, so that's it's virtually impossible to re-enable features that have been fused out. It's certainly impossible to do purely in software.
Never underestimate the bandwidth of a 747 filled with CD-ROMs.
The numbers they are distributing are the prime factors of the RSA key used by the calculators. The factors were determined by a general number field sieve calculation; this was effective because the keys are only 512 bits long.
The public key itself - the modulus - might be subject to copyright. However, the prime factors were never copied from TI - they were mathematically determined from the modulus. Attacking them because they distribute numbers mathematically derived from a copyrighted number is new legal territory.
If numbers derived from a calculation on a copyrightable number are themselves "derivative works" in the copyright sense, it would cause far-reaching problems well beyond calculators. For one thing, it would be illegal to distribute SHA-1 hashes of copyrighted material without permission.

Well, stick around some more, because it's not what the DMCA is designed to prevent.
As others have pointed out, you can only invoke the anti-circumvention provisions of the DMCA if the technological protection measures are controlling access to a copyrighted work. Simply bypassing a measure alone is not a violation of the DMCA.
In this case, they obtained keys that allow them to install custom software on the device. Where that software comes from may be a copyright issue, but that is not relevant to the overall matter of whether obtaining and using the keys is a violation of the DMCA. These keys control whether the hardware accepts given software; rather than controlling access to copyrighted software, the keys, in a manner of speaking, control the software's access to the hardware, so it's not a matter for the DMCA.

Because in the case of direct tv, you're paying for the service, not the hardware. If i go down to Best Buy and shell out $200 or whatever for a new TI-89 Titanium (my classic TI-89 is starting to look somewhat stayed...), then I never need anything from TI again. I take that thing, and I'm done. No real need to plug it into anything; TI doesn't beam the CAS down via CDMA wireless signal like some sort of Kindle thing.
Basically, with the calculator, the hardware itself is the FINAL PURCHASE, whereas with DirectTV, you're basically renting the hardware as a means to access a service, which is what you're actually paying for in the end. Cheating on what you're paying for as far as channels go is clearly wrong. Modifying a piece of hardware that once bought never needs to have any interaction with the mother company again is completely different.
Although a Ti-83 can definitely be enhanced by a custom OS, the usefulness of a Ti-83 would greatly decrease for students if custom OS's existed. On many standardized tests, including the SATs and ACTs, the tests specify which calculators are permitted for the test. They have a very specific list, based on which ones they think are not too powerful and would give an unfair advantage to a test taker. All ti-83's are allowed on either test for example. But if the makers of the test knew that people could have ti-83's that had undocumented, unfair functions (such as symbolic algebraic solving as in the ti-89), the test makers would most likely disallow these calculators. Why do you think TI still sells the Ti-83 plus, a calculator created in 1999? Certainly hardware abilities and processor speeds have greatly increased in the last 10 years. The reason is that test makers will not accept calculators with very powerful abilities. They want the student to solve the problem and not the calculator. When browsing calculators at education.ti.com, each calculator has a page called "exam acceptance" (ex. http://education.ti.com/educationportal/sites/US/productDetail/us_ti83p.html?bid=2). That is because TI sells a large number of its calculators to students. The custom OS's could greatly hurt TI's reputation in the eyes of its biggest supporters: the test makers.

Point being, of course, that just because something is codified into law, doesn't necessarily make it right.

I fully support what the EFF do but innovation is not simply limited to America - can I suggest in future they use the adjective "human", rather than "American", in similar statements? Otherwise, they're just affirming the stereotype that many of we non-US residents have, namely that Americans have no interest in the world outside their own shores.
