I do see the benefit of the service, but I think it would be cool if they offered a self-hosted version. A LowEndBox for $20/year gets you a box and an IP to tunnel through.
I am using a free tier instance in GCP and using tinc to accomplish exactly this. It's not "click and play" but setting it up is simple. If I ever outgrow the f1-micro its easy enough to add another node with a public IP.
It has the added benefit of being a full-on VPN, though I don't generally use it for regular internet browsing.
