> Yet here it is. Google can offer their services and the legal system seemingly doesn't want to be involved. Why ?
The real question is why do people use Google to sign in to other services? It never even crossed my mind no matter how long I have had a Google account.
The authentication service should ideally be under the control of the user. At least, the user should be able to choose one that they trust. I doubt it's an accident that current authentication systems lack that choice.
One could even eliminate those same tasks (not wanting to remember a new password, and not wanting to use a password manager) by setting an unmemorable password and doing a password reset using a Gmail address every time they want to log in. "Log in using Google" basically does that same sort of thing but without the tedium of all the clicking/typing. The mechanism is much different but in terms of dependencies it's really the same.
