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!
Anyone with root (or equivalent) access to your pc could easily undo that though.
If they have root access to my PC, webcam access is arguably not my biggest concern
It’s not the biggest, but it still is a concern, and is exceedingly easily mitigated.
