Gotchas
Over several years of ISPs collecting and selling PI, everyone will eventually be profiled. Phones, gaming systems, TVs, computers and IOT devices slurping it all up. Politicians have these devices too, so their browsing history and life style choices will be stored and available to whomever wants to exploit it.. Tit for tat as they say.
I would not be surprised if future ISP service agreements state that you can not use any tools or services that prevent them from their legal access to customer data. . VPNs may face legal challenges. This was raised by a poster elsewhere and I think they have a point, so I decided to repeat it.
