it doesn't mean they are unhappy about it. Or more exactly that a fraction of them can even look for such a feature.

which is a feature, not a bug. Professional account, personal account, cooking-club account, etc.

That's a different issue.

In some countries, in Asia and Africa, a single device can be used by multiple people. Internet cafes are another use cases. And shiny tablets can be also for one family.

Basically
device != user != web service

And it would create big challenges in usability and privacy.
