Proper policing of problem sites?
So in other words, the media companies get to decide directly who is allowed to be on Google's search results?
Who decides which sites are a "problem"? as shown in this article the people already charged with policing are abusing their position of trust, what will they do when they have even more power to censor what they do not like even when it lies outside of their jurisdiction.
The real answer is to reduce their charges for their products to a level where no one can afford to compete. As with any premium/luxury product, if your price is stupidly higher than the cost for someone else to copy it then you create a black market. the media companies created the market for people to copy their products themselves, if they made their product so cheap and availible then there would be no benefit to competing with them.
Add in that the revenues for the pirates come mostly from advertising and you should be able to appreciate that they are doing to themselves.
So wholistic solutions are:-
Make advertising agents and the companies they represent responsible for where their adverts are shown - remove funding for pirate sites.
Remove the luxury/premium aspect of media, make it so cheap and availible that no one can compete by selling direct to the consumer
Reduce costs by stopping the legal efforts that have shown themselves to be completely pointless, media companies have created yet another set of hangers on by their approach
The price for movies/music/books is stupidly inflated so that hoards of hangers on can continue getting money for nothing. if you cut them out of the loop you get a market you actually control without the incentive for anyone else to compete other than on quality. The cost of prodcution is always going to be based upon returns, if you collect less then the cost of production goes down. No more actors charging millions to appear in your movie just because they know you are paying the real freeloaders that amount anyway. Think back to the early days of movies, actors and other production staff were cheap as chips but when a production sells for millions they of course what a fair share.
