They also monitor outbound streaming. I've twice had a documentary movie I was watching at a theatre stopped because so one was supposedly live streaming the movie to the internet. The second time it happened they stopped the movie until the person doing it stopped, only it turned out they made a mistake and no one was live streaming it at all - they just interrupted the movie for fucking ages because of wanky attitudes. What made it even more stupid was that it was a special screening for a one off event AND a pretty niche documentary that most people wouldn't give a fuck about let alone pirate 🙄
