I understand Henri's point, but I believe it based on speculation and not
necessity. I believe EME can function perfectly well on all OS/UA
combinations, and the issue of which CDMs will be available on those
combinations cannot be predicted. For example, I don't believe one can
claim with certainty that any given CDM will not be available on some OS/UA
combination, e.g., on Ubuntu/FF.

The choice of which CDMs can be used for deploying some given content will
be determined by the content owners, as is their prerogative. The existence
of the EME solution that supports a variety of CDMs will increase the
number of options for content owners.

There is nothing about EME that prevents it from being implemented on any
OS. Whether a given CDM is supported on an OS/UA combination or natively in
a OS is a deployment decision outside of the scope of the EME
specification. There is nothing in principle that prevents any CDM from
functioning on an OS. That's why this is a non-issue.

It is substantially different from the perspective of those content owners
and content providers that are actually delivering content. I don't feel it
necessary to repeat again the reasons I and others have cited before.
