Huh? Android, iOS, and macOS have their own versions of TPM, Microsoft is just late to the game, and it's slowly catching up.
Out of the bunch, Microsoft is the only one that even allows custom kernel drivers, since Apple deprecated them with macOS Big Sur, and iOS/Android never really allowed them.
I don't say Android or iOS is more open...quite the opposite.

Why do you think people want yet another platform but in the Microsoft-verse, you choose Windows because it's open and you can run ~every application on it. There is no catching up by closing down your hard-ware framework (aka OS)
I assume majority of people want a secure platform where they can run apps/games, without worrying about ransomware and malware.
For those few that want to test things or run custom drivers, they can still disable driver signature enforcement, but some features/apps might be unavailable in this mode.
