You're right: the big carriers don't have much incentive to deploy this -- yet. We think deployment will come through three paths: 1) virtual operators (MVNOs) can differentiate themselves by offering PGPP-based privacy-enhanced service, 2) big carriers (MNOs) will want to (eventually) claim that they are doing the right thing on privacy and jump on board, and 3) new regulations (in various U.S. states and post-GDPR rules that are being drafted) are stipulating that location data is private so it's better to not have it rather than have to prove that it's being handled properly.
