This is like, one of my top reasons for thinking there's undisputed superiority (FOR THIS USECASE) in Apple's platform. They own the full stack, so there's nothing to install and it does work exactly like you'd expect it to. Yes yes you have to then own their devices and I know not everyone is in love with that but if you want to consume content, that you pay for, and not fight against the tech you're paying for, it's either Apple or buying blu-rays
I suppose that addresses the grandparent’s concerns about ease of use, but it makes the problem of running opaque proprietary software controlled by the platform operator even worse.
