I never really understood the point of camera covers.
If my computer is compromised to the point where an attacker can access my camera and microphone, information from my camera and microphone are the least of my problems.
Sure, someone could grab all my files, email, etc. That would be damaging.
But if I'm having a sensitive conversation in my home/office with someone and the camera and/or microphone come on, that could be damaging as well.
FWIW, I use a camera cover and Oversight[0] to tell me when an application uses the camera or microphone. It doesn't prevent it from happening, but at least I'm aware if something is going on. The weirdest thing I've seen yet is that the iOS Simulator uses the microphone.
Now I'm old enough that there's money in the bank accounts I access online, and I can afford a home big enough that the room I use my computer in isn't the room I get dressed in and have sex in, absolutely.
But if I was giving a computer to a 12 year old or 16 year old - what else is the hacker going to take? Their online gaming account?
Per OPs comment - it isn’t about a compromised system for me at all at least. If I’m in a video conference at 6am in my pjs I’m just a button click away from everybody seeing me. Camera cover let’s me know I can’t accidentally do this (and it has saved me on multiple occasions).
