W3C DRM OMGzors

Oh sweet zombie jesus the DRM whining again? You can have fucking Flash (you goddamned savages), or you can have DRM and a nice native player. Ebooks and downloaded music are mostly watermarked and DRM-less (except on Kindle), but you can't do that on the fly with video encoding.

You aren't going to convince Sony/Netflix/etc to just give you non-DRM copies of a $100M budget movie or series. And once in a while I like a Guardians of the Galaxy, Inception, or Justified. If you don't, the presence or absence of DRM in the browser makes zero difference to your life. You're just bitching about something that doesn't affect you.

For a slightly more calm, less profane explanation, read Tim Berners-Lee's post.
