I used to be heavily involved in the TI programmer community. In fact, many friends of mine I met through this still vibrant community. During that time, I never thought TI would resort to a false DMCA take-down request to get people to stop reprogramming their calculators. Yes, calculators. People do reprogram them. and TI sent a take-down notice for the signing keys (2 prime numbers) for doing so. Yep.. kinda sad.
