Exactly. As far as I knew, EME was the solution to the problem they were talking...

its a standard for the sites themselves to run a certain CDM, its totally unspecified on the browser side

IE, firefox cannot use google sandvine, even if you have chrome installed, because it is not a standard interface from the browser's perspective.

CDMs are absolutely not browser agnostic like NPAPI.

The specification is called EME.

> Beginning in version 47, Firefox desktop also supports the Google Widevine CDM.

EME is the standardized specification on the browser side... That's all it is.

CDMs could technically only work for one browser via fingerprinting, but that could already happen without EME (or DRM entorely) using browser fingerprinting to only serve content to UAs the publishers "trust".
