Practically nobody runs a custom ROM or Linux in the desktop, and if you do, that's a self-inflicted wound.
Meanwhile I can get high quality streams in an anime streaming service called Crunchyroll in all my devices (including every browser in any OS I want), most because they don't care about DRM.
: It is interesting that for default they still require Flash for viewing video browsers (they have a HTML5 video player in beta, though). To think that HTML5 reduced our freedom compared to Flash is ironic, to say at least.
DRM hurts honest consumers and doesn't prevent piracy — at all. So why are we being pushed to accept this level of outside control over our computing devices?
