So in short, we can't name any particular executive at Adobe who we are
confident has been made aware of this issue?

Has anybody directly contacted somebody in authority in Adobe's open source
office and gotten as far as an actual two-way conversation?

And the queries (mostly to "support"?) have all looked like they came from
individuals, or at best on behalf of an open source project (apologies, I
know the importance of this particular project, but the people receiving the
queries may not)? Has anyone approached them as an authoritative
representative of a company or product that Adobe would consider important?

I think I might have ways to make progress on these fronts, if anyone is
interested in the help.
