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!
A USB switch or the more expensive KVM could work.
KVM switch looks like it could work, since I don’t want to switch a USB switch and then still have to switch monitor input. Just need to find one with both an HDMI input and a DP input.
