“If you jump on my shift, that’s just rude, man.”
I think it's the latter, not the former.The reality is that it is easier for someone renting their airplanes out to simply say "no" or have restrictions on their use. It helps reduce the opportunity for stupid-pilot-tricks, as well as reduce the company's exposure to legal action if pilots do anything stupid in their airplanes.
Stupid pilots are going to do stupid pilot tricks regardless of whether or not there's a camera watching. Having a camera watching only increases the likelihood of Inspector Joe from the Feds finding out about it, and investigating.
