Apple just wants to get in on the ground floor so they can shape the legislation to benefit themselves. There's no way in hell a company as blatantly anti-repair as apple has suddenly decided to shift it's priorities when it makes them absolute bank.
They make far more money on margins for their tightly controlled parts doing the repairs themselves in house than letting independant repair shops do it for them. There's a very clear reason why companies like apple/john deere are so anti right to repair. They make shitloads off of being the place to go to "repair" your device at an insane markup(to discourage repair in the first place.) And if you don't like it, you can just buy a new one of their products. So they win either way.
Letting independant repair shops replace a chip for a couple bucks in parts andmaybe $50-$100 in labor absolutely eats into their margins and they see none of that money. It's a big reason why they control their supply chain so tightly and do stupid things like serializing parts and programming/pairing parts together. So other shops can't do the repairs they themselves can do.
