Why? Because I can't set my prefered GPU with uefi enabled (which is required for secure boot), and I occasionally passthrough my windows disk to a VM when I'm dual booted into my Linux OS (so naturally windows can't use the tpm).
Well yes, that windows was basically a direct competition to android (or tried to). Not sure what has TPM to do with anything really, but regardless;
I am not saying that Microsoft is pure hearted angel that would never dare to restrict client's freedom. Obviously they did it before many times and certainly will in the future.
What I am saying though, is that for now, Android is on completely different plane of user restriction then Windows (in it's main version) is. And even if Windows is constantly looking for opportunities to tigthen it's grip, none of the restrictions that are implemented right now can justify the conclusion, as if Windows is becoming so restrictive that it's reasonable to compare it to Android. Criticize them all you want, I will as well. But let's not bend the reality just so it's easier to say 'all corpos bad', rather then putting a small ammount of effort to distinguish between the levels of opression
