We will get there at some point.

But U also need to look at the barrier when registering an account for ur family members, it will not allow u to create another account from the laptop if u already have an account & using it.

Everyone that wants to sign up, I use their device to sign them up, not mine.

It is not possible always for a family and for every family of 4 members to have 4 independent devices, and moreover 4 different internet connections.

On Facebook, we don't have such limitations for obvious reasons.

And in the context of abuse, that can still happen with 4 different devices.
