There is a mitigation provided by PGPP, it uses a zero'd out IMEI, and some other cool things to thwart triangulation, reducing the precision to an area instead of a pinpoint. I think an important factor is number of users for the "hide in a crowd" effect, and I don't know anything about how many users they have. Also I want it to be open source but given their background I doubt it ever will be, it would have to be re-implemented based on their white paper. https://invisv.com/pgpp/
