> Cameras and microphones and write enable must have physical switches, not software ones. When will people learn?

Your preferences are not everybody's. Personally, I'd be totally fine with a camera and microphone LED that is guaranteed to activate whenever there is power/signal flowing from either.

> Me, I unplug the camera and mike when not in use.

That's a bit hard to do on a laptop that has both built in.

The Framework laptops have two tiny switches near the camera that physically turn off the mic and camera, and it presumably wouldn't be difficult for other manufacturers to follow suit if enough people cared.

I used to design airplane parts and systems. A guarantee isn't worth squat. Being able to positively verify it is what works.

You're right that I don't use a laptop for videoconferencing. I wouldn't use the builtin mike and camera anyway, as a 5 cent microphone can make it hard for the other party to understand you. I use a semi pro mike. If you're in business, I recommend such a setup.
