I think banned it a bit too strong. However there needs to be strong regulations on what can be shared.

If I go to an ER in a different area (read different medical system) I want my doctor to share personal data. I don't want my doctor to share my personal data with a random doctor in the same medical system unless that other doctor is an expert being consulted on something about me. (that is just being a doctor doesn't give you access to my private information, it needs to be on a need to know).

The above is the obvious case. There are likely other cases that are not obvious where after looking closely private information should be shared. Advertisement is never one of those reasons though, and analytics is only a reason if they anonymize the data with prison terms for mistakes.
