When you use your car’s built-in speakerphone feature, the speakers in the car door reverberate, sending the sounds outside of the car. Maybe don’t do this while your car is parked. Everyone in the neighborhood or store parking lot can hear your very intimate or business-related conversation.
YSK: When you have a phone conversation, there’s no privacy
When you use your cellphone’s built-in call feature, the antennae inside it radiate, sending signals to your carrier. Maybe don’t do this while living under fascism. Everyone in the corporations or government can hear your very intimate or business-related conversation.

The bad guys can intercept your convo in a MITM attack by simulating a tower and getting your phone to connect to it.
But they don’t even have to do that: all it takes is subpoenaing your carrier - with a national security letter to keep it quiet and make the unconstitutional a-okay - and your carrier will gladly hand you over to them like a pig on a roast spit.

True enough, but can you more closely follow the format of OP for my amusement? I cut the part about collection centers for rhythm ;)
