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!
Youtube has helped me save on so many home repairs. 400 service calls become a 30 part and an afternoon of taking the dryer apart with video guides.
