My thought is someone owning the rights to something in CountryB, but CountryA’s TV service is openly broadcasting it, which is fine if you’re in CountryA, but not elsewhere.
Just checked a copy of repo (won't link here). A lot of cable-only channels that are definitely not offered to the public. It seems that the repository accepts any and all links, including links that definitely smells unauthorized (IP-only stream links that correspond to residential IPs in eastern Europe or south-east Asia, most legitimate free IPTV streams are hosted either in Akamai or IBM's whatever-they-call-Ustream-now).
