It's indeed good for the org that all this is out in the open, but this brush-off is not a good way to start convincing people that you're willing to take criticism seriously.

Totally. I would feel a lot more hopeful about the fact that so many folks are talking about these issues if I thought that the board would be in a position to work on them. But at this point, I'm not so sure.

Thank you for the excellent comments you've left on astolat's post. You raise good points that deserve a thoughtful response, even though I fear you are unlikely to get one.
