it doesn't mean they are unhappy about it. Or more exactly that a fraction of
them can even look for such a feature.
In most cases ordinary users (not geeks) can not think of a feature, before
software developers provide it to them.
Second, user accounts are based on e-mails as a rule, which is not unique at all, every user can have multiple e-mails and
multiple registrations.
which is a feature, not a bug. Professional account, personal account,
cooking-club account, etc.
Who should decide this for a specific web-service? Apparently web-service knows
better is it possible to
have multiplicate accounts or not.
Many web-services struggle against users' reputation spoofing made via such
fake accounts.
That's a different issue.
No. This is related issue.
Multiple browser profiles on the same device do not matter, because the same
device ID will be returned.
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.
I know. In some cases a single e-mail is used by several persons, so what?
Basically
device != user != web service
This is true, but this is not a reason for not providing a device ID.
The main point, if device ID could be available it would provide more great
possibilities for users and web-services.
And it would create big challenges in usability and privacy.
These problem are already here. Device ID will add a new (optional) tool to
help in solving them.
