We remain in a "crypto winter.” The blockchain company that runs the downlink is likely looking for business. The elephant in the room is the coming Chinese crypto-Renminbi with Libra bring up the rear. The small crypto-currency companies could be wiped out by the big operators. They are already pirates according to the Banks. So, this doesn’t make much sense. Also, many of the early crypto companies have loads of cash and would be interested in supporting an infrastructure play like this. There is also a $100,000 "bug bounty” now for anyone that can hack sensitive documents from inside the big security/intel companies. This type of move might get support too.

I don’t know the details of those phones, but location is trivially spoofed on most phones. 
Physically, the beam is likely narrow and hard to locate from the ground

As far as I know, incoming channels are not affected.

Most of the traffic on an Internet connection is download.
So, if that could be off loaded on to the satellite, it would require very low data rates in the mesh network.

Normal phones are limited to 10 meters, but special antennas allow about 50 kilometer line-of-sight communication. When there is widespread resistance, a mesh network can be created from thousands of phones and a signal can propagate from one to the next, as long as there is no wide gap.
