I guess I was unclear: that could probably be reworded to say "I don't think anyone specified GPS"

That ggp prefixed that line on AGPS with "even"; they were asking for citation that Google persistently tracks location, and just used AGPS as one example.

The point being, saying Google allows you to disable GPS is a world away from saying Google allows you to disable location tracking. And I'm not talking about IP geolocation.

I don't even know if they do completely respect your choice to disable GPS (citation needed indeed here), but I do know that they persistently track you via WiPS/WFPS at the very least, if not other methods.
