The free link sites are full of ads and pop-ups too, I doubt any of that revenue goes for copyright payments though I could be wrong. I don’t see those ads because I have a host manager and pop-up blocker.
But the original ads in the recorded show couldn’t be blocked, though one could advance through them.
And the networks could charge more since ads are priced, partly, by how many see them.
The video sites I use are licensed. They are only available for the regions licensed too. It’s annoying when a show that sounds interesting is not licensed for my region, but North America rarely gets that. I guess those smaller countries like the attention this brings.
