Yes. Comcast and other big ISPs think you belong to them, that other businesses should pay to get to you, despite the fact that you, the ISPs actual customer, already paid so you can get to those businesses and they can get to you.
And yes, TLS doesn't conceal the domain names from your ISP and that's all they need to pick winners and losers. It can somewhat conceal different kinds of connection (e.g. peer-to-peer protocols like BitTorrent) but those aren't hard to spot through traffic analysis and Ajit Pai explicitly thinks ISPs should be able to block them, as Comcast was doing to BitTorrent traffic.
