People have warned about this since the inception of Android and how the supposed security of a centrally managed software store will lead to restrictions.

This is why "computers" like Chromebooks are useless as well, I wouldn't even let pupils have them if the goal is to teach digital and technical competence.

I don't believe these restrictions will be successful on a PC to such a degree. Remote attestation does exist though and I recommend to leave it for remote machines managed by yours truly.

Usually phones are technically quite capable, but the OS landscape seriously inhibits innovation.
