I agree with you on some Thunderbird bug particulars, and I weighed in and in at least two cases helped turn things around:

https://bugzilla.mozilla.org/show_bug.cgi?id=668655

https://bugzilla.mozilla.org/show_bug.cgi?id=579372

https://bugzilla.mozilla.org/show_bug.cgi?id=478468

Sorry I was not earlier on the scene to help -- people are supposed to mail me when my early warning systems don't see a problem in the community.

Honest question: did you try to intervene or get involved in any of these cases?
