Until a better solution is found, I think the way the recent IOT botnet stuff + this ISP privacy deregulation is portrayed in the media opens the opportunity for a startup that sells a secure, smart home router + VPN subscription plan.
And you would trust the startup with your traffic because...?
Do you trust any VPN providers? Or your ISP? Or the programmers of the browser that you're using? Or your CPU manufacturer? It's turtles all the way down.
Perfect is the enemy of good. If that protocol was open, it might foster a way to fold VPNs into the everyday person's internet connection, with the possibility to easily change VPN providers down the track.
