The point of my qualification was that my main point is independent of
what you think open source means. You can certainly implement EME and
a CDM under whatever open source terms you choose.

It's frequently claimed that DRM goes too far in controlling usage to
align with content license terms. So, presumably, some people would
like to see other solutions that do not go so far. I don't know what
those might be, but EME provides a place to experiential with such
things, over time. Maybe that won't work. Maybe there is a
mathematical proof that anything short of DRM as it is today is
equivalent to clear key for some kind of equivalence accepted by
content producers.

The point is that whether a useful CDM can be built in open source is
clearly not a technical issue. It depends on the ingenuity of people
creating CDMs and the requirements of content producers.
