I think it's the fact that anyone can become an iptv reseller because of how it's sold so most people buy it from a bloke down the pub, a telegram group or someone on fb marketplace or someone who knows someone on a forum, so that gives you the acceptable friendly face as they're usually on a page or a group taking requests and sorting issues out etc
These people aren't the people actually providing the service though, there's a few large groups that do it and it's sold on en masse
Jokes about sky aside, it's a big source of money laundering funds and finance for bad causes for these groups.
