1. VidAngel purchases a bunch of Blu-ray discs and stores them in a warehouse
2. Tag all the content of a film and create filters so the user can, for example, filter out all sex and violence but leave in vulgarity
3. User "purchases" a Blu-ray for $20 (!!) and VidAngel says, "since we now know you're the owner of this copy sitting in the warehouse, we'll stream it to you right now instead of going to the bother of mailing it out" (This part legally qualified as a "performance", which was their big mistake.)
4. When user is done watching the film, VidAngel automatically buys back the Blu-ray – still sitting in their warehouse – for $19.
So users could essentially stream any film they want (with optional self-selected censorship) for only $1 per viewing. Of course they get a flood of users since they're the cheapest shop in town, and of course since what they were doing was illegal they got taken to court and had to shut down 90% of their business.
And then, they wrote an endless tream of publicity saying, "Big media doesn't want to give you the right to skip nudity and violence in your own home! Think of the children! They want to force their values on you!" Yeah, I don't think the film-makers loved the censorship platform, but it was the $1 performances that really got them riled up.
