The Electronic Frontier Foundation (EFF) warned Texas Instruments (TI) today not to pursue its baseless legal threats against calculator hobbyists who blogged about potential modifications to the company’s programmable graphing calculators.
TI’s calculators perform a “signature check” that allows only approved operating systems to be loaded onto the hardware. But researchers were able to reverse-engineer signing keys, allowing tinkers to install custom operating systems and unlock new functionality in the calculators’ hardware. In response to this discovery, TI unleashed a torrent of demand letters claiming that the anti-circumvention provisions of the Digital Millennium Copyright Act (DMCA) required the hobbyists to take down commentary about and links to the keys. EFF represents three men who received such letters.
MAKE was also told to remove our post (here) – we did not… TI is a great company, I think once the folks who run show see what’s going on they’ll drop all of this…
