There was a long thread discussing the semantics of "open web" and "open". I do
not claim that there was or is consensus regarding the semantics or the
suggested test. Here is an entry point:

The W3C officially has stated that it supports an "Open Web Platform". Before
EME there were no differences regarding the semantics of "Open" in that
context. This has changed. Some people within the W3C now would like to
(re-)define it in a way which is incompatible with open standards and Open
Source.

A standard which in practice can not be implemented using the GPLv3 is not
open. EME in practice can not even be implemented using the GPLv2.

As I stated in #c15:

"Fixing this issue without canceling EME is (almost) as impossible as designing
a working perpetuum mobile. For that reason I can not provide a change
proposal."

Another change would be for the W3C to officially declare that it no longer
advocates the "Open Web Platform" but only a "Web Platform" (whatever that is).
