I don't see why one user would not want to reveal his location, because
he already send it regularly, although less precisely, to his telco
because that's how GSM works. AFAIK, telcos are then free to use this
information commercialy and forced to give all details to the cops when
asked to, so I don't see how this app could make things worst.

Did I miss something ?
