If the vast majority of people on they host were selling access it makes sense. Users don’t want to hear it but Plex has to shield themselves from lawsuits. If you willfully let people break the law with your product as a feature you have no argument in court. Same goes for why they add all these features they core users don’t want. They need a reason to argue that they don’t just make money on piracy. FOSS doesn’t usually get sued though, but nothing is preventing it. Everyone needs to be careful and if your going to illegally download movies don’t be greedy and sell access to it.
