That's what the judge agreed with: it's unreasonable to require you to block all Internet traffic with the assumption it's all VPN traffic until proven otherwise.

Under Utah's law as written, a private business has to assume any single IP address could be operating a VPN/proxy.

He said nothing about traffic type, that will always be HTTPS and websocket stuff. Nothing out of the ordinary to block there VPN or not

With cross tunneling all your normal traffic would go through your ISP usually and just your porn traffic goes through the VPN. Unless it's a major provider, as far as your ISP is concerned you're just connecting to someone's private server occasionally
