It being difficult is different from it being possible. If a company wants to raise $50m to read all the documentation and build an alternative OS to run on this crazy piece of hardware, as the consumer I still benefit. If you'd prefer, let's stick with repair? I also need all of that information to be able to repair my phone, but again, it wouldn't necessarily be ME who repairs my own phone: I take it to a third-party expert who has built out their own expertise and tools.

(Hell: I'd personally be OK without "documentation"... it should simply be illegal to actively go out of your way to prevent people from doing this. This way you also aren't mandating anyone go to extra effort they otherwise wouldn't bother with: the status quo is that, because they can, they thrown down an incredible amount of effort trying to prevent people from figuring things out themselves, and that really sucks.)
