You have to make do with what you can. At the moment, any more legitimate form of content monetisation is effectively ruled out by the "rigid", as you call it, stance of the copyright holders. I'm sure the people setting up those sites would rather use more profitable business models.

In fact, if you read the article, you will see a screenshot of one enterprising bit-torrent site offering monthly subscriptions. So even with all the hurdles thrown into their way by the current owners of the time-unlimited copyrights on these works, they still manage to do more than just spam portals.

I think that's to be applauded.
