I remember a while back Apple filed a patent that allows concerts to disable iPhones cameras if a certain signal is emitted from the stage. Apple never implemented this, but my pessemistic ass always try to think of worse case scenarios, like being used by government. Do you think this could occur in the future?

You can search “Apple Concert Disable Camera” and find more about it.
So you are just describing a security camera?
The camera part would work as a normal camera, sure. However, the fact that it would turn on whenever it detects the ‘don’t record me’ signal is an additional feature that provides context to the video recordings and also logs all times the signal is detected and used.
So similar to the way other popular security cameras provide new features, e.g. a camera that only records when motion is detected.
Anyway it’s something I literally just thought up in 15 seconds. Obviously it would be unreasonable to expect a polished, viable, feature-complete product idea. Which are a commodity in any case :D
