I think your message is a starting point and written well because:
-you point out issues
-you tell to whom and how does maintainers decisions affect on potential
visitors
-you give suggestions to fix them.
provides -> providing ;)
-It affects also other communities than the Free Software Community. I mean
the users of software, which doesn't have a flash implementation (yet).
I also second to jxself's point, one should indeed write in their own words,
so the response would be something else than pure ignorance. "oh, it's this
spam again".
