Out here, some people pay for a "flat fee mobile internet" connection. 

If you send a 0.5k UDP packet, containing where you've been over
the last few minutes, this would be nice data.

This is an issue. The phone company already knows this, and they would
get into a big scandal if they suddenly started selling that data.

For OSM, this type of data should also lose the identifying
information as soon as possible. But the people having "root" access
to the server will always be able to put one and one together. (this
is no different from those having "root" at the phone company. But
those guys are bound by an NDA).
