For me it’s the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they’re being spied. Here’s the secret - unplug the damn thing when you think you won’t use it or haven’t used it in a while.
They, whoever it is, can’t really spy on you on something that’s already off and unplugged!
That assumes you can unplug it. Most devices I own have the camera built right into the device, and it can sometimes be hard to find an option that doesn’t include it. I have a Webcam cover on my desktop and laptop.
I haven’t seen one that would work for my phone, but if someone has hacked my phone, I probably have bigger issues.
That, and most people don’t know how to disable the device from their device manager.
Is it a monitor provided by your workplace? If not, well, it’s not that hard to find a monitor without a built-in camera. I found one easily enough for my gaming desktop… Unless the monitor market has dramatically changed since 2019-ish…
