This is false. EME describes only the interface between the Javascript environment and the CDM. It says nothing about the CDM's interface with the browser code, which is the heart of the issue.

You're rebutting an argument I didn't make. The CDM is closed-source, but it was closed-source in the pre-EME world too. My argument is that EME opens up DRM stacks; it's that it opens up more of the DRM stack than was open before it.

Your argument is that EME covers most of the code responsible implementing DRM. This is false. EME is a small part. The large majority of the implementation is not standardized. For example, there is no equivalent of NPAPI in the post-EME world; the CDM/browser interface is browser-specific.
No, that's not my argument, as you can see from my comment above. What you've done here is twist my argument around to introduce claims I didn't make that you find easy to rebut.

Is there another interpretation of 'everything' in this context? You're making EME far more comprehensive than it is. CDMs do way more than derive a key, so your statement is false on its face.
