From what I have read, you own the equipment. They have a $100 installation fee. < which most people in 1st world countries, would not be able to afford > I think some countries might subsidize this cost or merchants might help to provide satelite hubs for people to use these services.
The innovation will come, once these installations are done. < People find ways to make things work >
OP, Satelites are not bullet proof. Some countries might target these satelites in war times. < take down the satelite and you take down most of the communication and equipment that rely on GPS coordinates. >
