Just one last point, which is that such objections are not objections to
EME per se, but to the entire domain of content encryption as it has been
fielded in the past. I'm not sure any adequate, substantive response is
possible, since the same objection could be made to any proposal to support
content encryption.

For example, an alternative proposal might be to reframe EME as an
extension to TLS that would allow a pluggable key and encryption method in
TLS as well as a JS API that interacts with TLS that serves the same
functions as being proposed with EME. The only really new aspect of this
would be the JS API, since TLS already supports arbitrary encryption and
key types (as chosen during the initial handshake). It seems to me one
could potentially make the same objections to this reframed proposal as are
currently being made for EME, yes? Which, if so, shows that the objection
is not specifically related to EME as such.

At bottom, the objection seems to be with the past business practices of
content providers (driven by content owner licensing restrictions). The W3C
doesn't seem to have any control over such practice, and it seems unusual
to propose restricting W3C technical solutions due to past business
practices in another solution domain. Even if such business practices
continued, would that be a legitimate reason to block EME, which can
certainly serve uses that don't follow such past practices?

I think this is all I can add to this thread, so let me make this my last
reply, unless you wish me to answer something specific.
