If they are using a decent ad blocker they probably dont see 99.9% of that. At most they might note one of the couple mirrors for the video doesn't work.

Well, if you are an experienced pirate, this is not an issue. You have an adblocker that filters out all the stupid ads and scams, and you only go to a few sites and know which links you should click. Getting that kind of experience won't take more than a few hours.

There's an app called Stremio that just blows any "official" app away. The app is not for piracy per-se, but it's easy to turn it into a full fledged PopcornTime version that works.

Yeah, but it's obvious. Obvious malicious design is easier to filter out than dark pattern design.
