This is the next shoe to drop.
Comcast currently extracts almost $100 a month from me, in addition to the ~$10 I pay for a VPN exit node to hide traffic from their surveillance machine. Why wouldn't they want another $10 or so to "allow" VPNs, given regulators who are loudly, publicly giddy about screwing consumers?
This is a goldmine for ISPs. Over the last five-ish years they decided to think of themselves as "advertising" companies. FCC repealed the internet privacy rule last April, and what are they doing now? They're functioning as data brokers. We should expect this trend to continue and assume that ISPs will take advantage of Pai's NN repeal as soon as possible.
