I think this is a bit of a weak argument, the overwhelming majority of creative works are not sold by the creator themselves.
I've now bought a blu-ray player 3 times from Cyberlink. What's going to happen to my blu-ray player when they go out of business? I doubt I'll be able to get it to play blu-rays at all unless I find a crack somewhere. The software I need to play the media I own is DRM'd lol.
