I still don't understand how someone is supposed to benefit from such a thing. If I want to use some service, I'll sign up for an account with it. The only thing a centralized ID is going to do is let the service correlate me with a different account on a different service, which is exactly the thing that I don't want.
How is someone supposed to benefit from a thing whose only function is to reduce the friction against forcing them to correlate their otherwise-independent activity against their will?
