I wonder if EME or some other similar mechanism in the future will be used to create websites that can only be viewed by certain browsers and/or operating systems? Perhaps even prevent you from copying any part of them or download anything from them? Maybe Web Assembly will also play a role (perhaps as a DRM'd browser "wrapper" to view content through) - it would be like using a DRM'd browser "window" via Flash or something. Where any browser can view the content, but it is impossible to get any of the content out (because no one saves bits of conversation from blogs or anything like that - and all websites will always exist). Hmm - indeed, imagine if you couldn't copy twitter feeds or facebook posts (and they were DRM'd in such a manner that trying to do so would be a violation)...? All of sudden, people could erase posts and claim they never said it, because there isn't any copies of it around (today, they have to get lucky and hope nobody made a copy first).
