The Encrypted Media Extensions (EME, a.k.a. DRM in HTML5) specification is not a real DRM itself. It provides for add-on parts described as Content Decryption Modules that provide DRM functionality for one or more Key Systems. DRMs are obviously designed to be non-interoperable, and EME is a standard for managing such non-standard stuff. That is going to break interoperability, as any given browser will inevitably miss some decryption modules. Internet, globalization, and the information age may well entail a change in the basic principles of economics. However, IMHO, DRM is not a solution to copyright infringement, not more than postage is a solution to spam. Injecting DRM through EME is a disservice to web standardization, since the latter is supposed to foster the Internet revolution.
