I assume you mean a "Proxy as a Service" when you say "VPN," right? Without that focus, web sites would have a lot of trouble identifying IP traffic routed over a personal VPN from any other traffic. I suppose they could just block entire clouds, for those who run VPN servers on AWS, Azure, et al. But that would cause a lot of other problems. I just route all of my devices through a single node I run at one physical location that appears like a genuine client node. I've never seen anything blocking it.
