I was listening to Matt Bracken on Rumble, and Matt brought up point I had not considered.
Israel just demonstrated a capability that should make all of us pay attention: the state use of wireless devices to execute a mass time on target attack.
What if, in the future, someone does this to cell phones of MAGA voters? Or, to get at Elon Musk, they do this to Tesla cars?
Almost anything that is connected to an outside network can be hacked. And backdoors exist and are intentionally introduced/not patched for government agencies. 3rd parties can obviously also find those then.
Keep in mind though that these were compromised pagers specifically sold to them, not random stuff picked up on the normal market. To target MAGA voters you would need to sell them a special "MAGA only" phone.
That said as soon as your piece of hardware leaves your eyesight it can be considered compromised. See airport checks.
