Not sure which is winning here... but trying to force users to only use your materials in your device which is designed to go around copyrights, patents, and trademarks by letting me make my very own Left Shark is definitely a trophy-winner in one (or both) of these categories. Might even make Honorable Mention in the Massive Entitlement Based Ego category.
this is the way it used to be - without any law being required... Sams PhotoFacts sold "repair manuals" for every radio, TV, and other electronic device - to repair shops that used to be more prevalent than coffee shops today. Even to home "hobbyist" electronics guys. We'd crack open the TV, pull the tubes, wander down to Allied or Radio Shack or Heath, test the tubes, buy the replacement parts, pop 'em in, and have a repaired set. And we even built our own TVs from kits...IIRC, you could get an Associates Degree in Electronics by building one of the big Heathkit TVs.
But the downside (from a certain point of view) - people repaired and kept equipment for many years - they didn't buy new every time a new model came out, so that had to be stopped. And the manufacturers got away with stopping it.
And I doubt this law will be able to fix it (pun intended)
