Sure, from and individual perspective. What if I want to build software for people who use the iPhone and I want to add some web3 functionality and Apple says no? Apple basically does stifle innovation on their device by acting as a regulatory agency for their users. Even MSFT didn't do that. Basically every iPhone user is on a closed system that one company controls from end-to-end. That's a type of market power that we haven't seen since maybe the railroads were controlled by 3 people.
