Maybe they don't need DRM or IP. They'd get more money from me if they were paid to distribute the media. I'd support that.
As for game developers, they could make a lot of money if they just got funding from people who were interested in the project. They then wouldn't need it. If I used it, I'd donate and if I was interested in a project, I'd pour some money into it. They would possibly make more money that way because the people who funded the projects would be satisfied with it because they'd be likely to demand that the game meet their expectations.
They could get paid by advertising other companies' products. That way, you don't need IP and it may even be undesirable. IP is for people who aren't creative enough to make a profit via natural means. The end user doesn't have to pay for the creator to make a profit. Hell, if I started a game company, I'd do what facebook did. I'd have the best, brightest, and most creative ad AND game creators. In fact, I advise all start up game companies to do that and just hope that that business model wouldn't be patented.
Sure, they wouldn't be guaranteed a fixed profit, but IP requires action on someone else's behalf.
There is the model I mentioned above. Feel free to criticize it, but it hasn't ever been tried by any game companies I know, so it could make them 10x what they make via IP for all we know.
