I think they've got to be licensed for US customers, or T-Mobile USA isn't going to include them. Twitch does seem to be a notable missing provider; Amazon video is on the program though, so maybe there's some technical or product thing on Twitch's side.
Even US-only. Broadcast networks category is especially slim. They've anticipated this kind of scrutiny and claim no money is exchanged, but idk. Someone should try adding a random obscure service.
