Google did make location history private in the maps app(delete on server side) at some point, if I recall correctly everyone can at the least opt in(i may be wrong and it may even be opt out!). I believe out of the exact concerns of warrantless sweep of all location data of all users around a lat long for server side storage by law enforcement.

It went under the radar but is a good example of _some_ incremental positive improvement over centralized storage.
