This type of camera use at concerts or stadiums is decades. Although I agree with you, the biggest concern are things like Nest cameras that film random people walking on the street. Or general government surveillance.
In the UK, some guy got arrested because he refused to show his face on a street surveillance camera on principle.
I use Freetube on PC and some NewPipe fork AND Freetube on Android. The Android one has been breaking as of late. :-(
