You have to think about the trade off between not having remote accessible cameras versus having them. If you can make systems more secure by eliminating them, you can become very secure and simultaneously not very useful.

Not having remote accessible cameras would seemingly make using the cameras take longer or be less efficient. In turn, that might make detecting or tracking physical intrusions less efficient and/or less successful. Should Cloudflare take that trade off? I think it depends on their threat model.
