Let say Billy wants to be a live streamer on twitch or YouTube, but remaining his privacy as possible while still able to have great streaming performance. Will you suggest Billy using VPN for live stream?
Well it can’t hurt, but I’m not sure it would help either. It depends on Billy’s threat model, is Billy mostly concerned with staying private with respect to his/her viewers or private from the streaming service itself?
If the former, I would assume whatever service Billy streams on would be preventing viewers from seeing a true IP or anything like that, so I’m not sure if a VPN would have value. If Billy cares more about privacy from the service itself, this is a much harder problem, a VPN would help in this scenario but it wouldn’t be a magic bullet Billy would need to take other steps and develop good habits.
