There's something to be said for the more recent thinkpads that have physical sliders built into the laptop.
I can't paint on it without trying to unglue that and ultimately break it.
I don't think they would actually use the bypassable filter in everyone's camera, maybe just political dissidents, but having the red dot be the standard would make it less noticable when a bypassable filter is deployed.
We just slide it half way, then there's no irritating red dot and the camera is still covered.
A little Ghostbusters symbol - even in red - would work much better.
Ultimately Apple should probably build this in given their “privacy” messaging.
But in any case, I think surreptitious microphone access is a bigger problem than this, and there’s no easy solution to it.
I would like to see more and more of these physical kill switches, hopefully kind of like the silent switches on my iPhone, but maybe with little sliding locks to keep them in position.
I think there's a pretty healthy market for privacy/security/control-oriented hardware.
I find this popular trend of webcam sliders for purported security reasons is mere security theatre as long as microphones cannot be physically disconnected.
