Their power is very limited, so really all they've been doing is nipping around the edges. Their goal is to expand that power technologically and legally in order to both stop piracy and make absolutely no concessions to consumer convenience, maintaining maximum flexibility in their choices when bringing sights and sounds to market.
All profits being held equal, the studios would prefer to charge $100 million a ticket and have you watch it in a closet in some LA office. The industry creates films that it doesn't care if anybody sees, and creates music that it doesn't care if anybody hears. That's the problem, and that's why we're surrounded by crap.
I'll tell you what kind of convenience I want: if I watch a movie that turns out to be deceptively marketed garbage, I don't want to have paid any more than those two hours of my life for the chance. I also want an easily streamlined, audited, and publicly supported way for me to support the artists that I want to encourage to create more things that I want to see. I don't want to be marketed to, I want to be asked, and I want honest recommendations from people who know my tastes enough to think I may like something.
I don't want glorified distributors being able to hold both the artists and the consumers over the barrel to move a product that doesn't even need to be distributed any more. I don't want my culture to be a patchwork of ownership, like the land became. If I hear a song, I can sing a song.
So, basically, I wouldn't happily pay $10 for The Avengers on my television, and at best that would be a partial solution for the industry IMO.
