Yep, but that's absolutely what's going to happen. People love to put square pegs in round holes. I'd be surprised if most things weren't DRMed within 5 years.
I don't buy it. People could DRM up the internet - including text and images - much more easily - for years with Flash and Silverlight. People could use the everything-is-a-DRMed-single-frame-video-now hack since 2014. Neither have been a problem. I've never even seen the latter happening, even as a proof of concept (although I suspect someone will point me to one shortly).
