To defend Redmond here, Entra is an enterprise system. If the company you work for or are interfacing with wants to enforce attestation, that's their business.
B2C I would expect more latitude on requiring attestation.

I think it's reasonable to have attestation for the corporate use case. If they're buying security devices from a certain vendor, it's reasonable for their server to check that the person pretending to be you at the other end is using one of those devices. It's an extra bit of confidence that you're actually you.
I once knew a guy who refused to let his office computer go to sleep just to avoid having to enter his password to unlock his computer. He was a really senior guy too, so IT bent to allow him do this. What finally made him lock his computer was a colleague sending an email to all staff from his open outlook saying “Hi everyone, it’s my birthday today and I’m disappointed because hardly anyone has come by to wish me happy birthday”. The sheer mortification made him change his ways.
