I’m boycotting Texas Instruments for all new designs I create until they pull their heads out of their butts and apologize to their customers for their stupid anti-consumer actions. Linear Technology, National Semiconductor and ON Semiconductor are now my preferred analog and power chip suppliers and I’ll go with Microchip, Zilog, Intel and Freescale Semiconductor for my microcontroller needs. I strongly encourage all other electronic designers to join me in boycotting TI products until they wake up and treat their customers fairly.
Briefly, TI has sent DMCA takedown notices to TI calculator owners who posted the keys needed to change the OS on certain calculators. This is almost certainly legally wrong since the DMCA has been ruled by the courts to not apply in a similar situation (Lexmark v. Static Controls). While TI has a lame excuse about keeping the calculators trustworthy it is ridiculous because they used weak fairly easily breakable encryption. If TI truly feels they need to keep users locked out, they need to make an effort and use a real lock not a toy lock. Whatever they want to accomplish, legal threats against their customers is not the right thing to do.
