Yeah I agree, it's more consumer friendly and mainstream than more "traditional" piracy, so the potential for IPTV to impact their revenue is much greater. Once you start getting into torrenting and usenet and the *arr suite, then it's a much smaller percentage of people with the right skills, equipment, and inclination to make it happen.
the only iptv I get is from the iptv github, never had any luck finding much else then that, especially since the canadian iptv website died, I do wish we had better free epg
