> Attestation is just an optional feature that expands what is possible.

So optional that everything that can require it will require it. Games want it because cheating. Streaming services want it because piracy. Banks want it because fraud. Web sites want it because advertising. Governments want it because encryption and anonymity.

> Services have no obligation to check attestation or use it as a hard signal to block people.

They will do so of their own free will.

> All previously existing freedom is still possible on your computer.

You're "free" on your paperweight of a computer that can't do anything useful because it can't interface with the rest of society. Maybe one day even ISPs will reject clients that can't pass attestation. Can't even join the internet if you "tampered" with your machine. Such is life in the land of the free.
