(I don’t like this kind of data collection either fwiw, not trying to defend them or anything)
On Android at least, device id’s are unique per app, and reset when you reset your phone to factory. In theory they can’t use this data to cross-track you personally, since every service that uses a device id has a different one for the same user.
They can probably still build up a pretty accurate profile of you based on other data they collect though.
Yes, that’s exactly the point. Combining data is something that must be considered. (And in some jurisdictions like the EU you even need to consider if it could be combined in future with other data)
