That tends to be the thing with most open source products. No money! That being said, Canonical is doing quite a bit. I've seen several computers for sale online with ubuntu pre-installed. I might be mistaken here, but I think a few open source projects have successfully defended their projects from companies ripping them off. Actually, there was an android emulator that was pulled from google play store and forced to release their source code because they were in violation of GPL (or some other similar licensing). In my experience, most linux users agree 100% with this. I don't think I've ever seen a linux user support DRM in music or media. And I believe a few different platforms for linux exists that sell DRM free music. Weird, I find linux users, forums, and IRC channels to be especially helpful. I don't know, it's good that you're able to find something that works for you.
