I recently learned that, just like most other businesses, a lot of free pirate streaming sites are actually powered by a few big content aggregators[1][2][3]. They don't do much beyond providing a nice-looking frontend to an unauthenticated API that those aggregators expose.
One could probably spin one of these up in an afternoon (if making money was not the goal). The barriers of entry to this ecosystem are a lot lower than I ever imagined.
Those aggregators serve their own ads (what you get through the API is a link to a web player embed, not to the video directly). I suspect that bigger sites get some kind of kickback for bringing in traffic to those players.
