Feeding any data anywhere is a concern.

German hacker association Chaos Computer Club found out that VW had collected location data on their cars on a badly secured system. That data was exfiltrated and it was shown that it could be used e.g. to determine where politicians lived, which schools they dropped their kids off at and which brothels they frequented.

Leaving data in the hands of a company subject to foreign jurisdiction is concerning but even within your local jurisdiction simple carelessness can lead to data leaks with potentially massive consequences. The best way to prevent misuse of collected data is to make sure the data isn’t collected in the first place.
