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.
Some monitors have inbuilt KVM switches, have an MSI ultrawide (model escapes me sorry) I bought a few years ago that I use to flip between usbc and dp. Configurable though, could set it up to flip between HDMI and DP and assign usb to whatever one I prefer. It’s way nicer than the switch + swapping inputs manually I had been using.
