The web was more open when to play those videos you had to use a proprietary Flash or Silverlight plugin?
That's what you are claiming with your sarcasm hidden behind a rhetorical question, I've never said anything about Flash or Silverlight in the comment you've answered to.
There is absolutely no difference from a conceptual perspective between EME implementation and proprietary plugins, EME is necessarily based on a proprietary spyware, but you can't fathom that fact apparently.
