I think it only benefits the film industry, particularly indie filmmakers looking for tools to help them self distribute.
I have pretty mixed feelings about “open source media.”
In the film world it mostly means torrents and other forms of promiscuous (and free) circulation. For people with no track record, it's a great thing. As an emerging artist, the greatest challenge is overcoming obscurity. So building an audience is far more important than seeing a revenue from their work.
On the studio side, I don't really believe it's as big a problem as the industry claims. I'm sure pirating is cutting into profits, but that increased exposure probably drives more merch sales, etc. I think where it really hurts is the middle class: the small to medium indie productions. It's a tough spot because a few thousand sales can make a difference as to whether your investors will come back for the next project. And it's become a common refrain amongst distributors who are looking to lower their purchase price.
In terms of tech, I think it only benefits the film industry, particularly indie filmmakers looking for tools to help them self distribute.
