Can't remove myself from family account

Hi sebadei​ - I think there is limited legislation on this topic yet. Yes you are accurate that you should have the ability to delete your data, but I think technically (as in legally) it's the account owners data which extended their (contracted) service towards yourself. Not trying to start a fire, and not a legal eagle by any means myself, but on technical topics it's worth comparing to cars mostly, bare with me, if you share a car with someone and it supports 'profiles' or whatnot (let's say it's audio system has support for some audio streaming service). If you leave that family or sharing and you (un)intentionally not deleted that profile - you could ask the car vendor/service technician to delete it but I think that is where legislation gets vague, because it really is 'your' data, but who's the grantor/holder in that case.

As you see from Simon's reply, they take it seriously (and good on them!) but as you specified 'business relation' which - again comparing to cars - is the owner of the car and not one of the drivers.
