In a worst case scenario: US Invasion. What device could the US government simply force to stop working in Canada that would cause the most chaos (e.g: brick all iPhones)?
Sat up last night thinking about Mesh comms for the average Canadian who aren't likely going to be running out to buy new products. As a back-up, I have Briar for groups and Bluetooth chat for 1-on-1, but wondering if there are any recommendations you or others may have that are 1) better and 2) a Canadian solution?
