When I buy something electronic, my approach is "everything that is closed and goes online will be used to spy on people". It may seem a stretch, but governments can't exercise power over something they cannot control, and truly private communications would take away some of that control. To me there are no conspiracy theories or other strange reasons for being able to decrypt any seemingly private information except the will to preserve the status quo at any cost, which implies knowing in advance what a potential adversary may think or do. I would expect every device to be bugged for that reason, including all cellphones and computers and associated hardware, from CPUs with closed subsystems down to network chipsets with closed firmware. There will be no way to ensure private communications until someone will find a way to make a device which is 100% open and auditable from the operating system to the CPU, from all chipsets down to the last screw.
