Regardless of whether Murray's recent rant is accurate or polite, I'm glad that he's aired his opinion.
Most of the board's processes and meetings happen behind closed doors. From the meeting minutes (and be honest here, how many people actually read those?), who can tell if member X is being derelict in his duties or being an obstructionist? Especially since the board members have an unofficial policy of not speaking negatively of past and present members in public.
Murray has been on several GNOME Foundation boards. He's seen how the process works and has a somewhat unique insider's view of things. I'm glad that he's broken the wall of silence.
How much you choose to believe Murray is, of course, your decision to make. However, attempts to silence him by telling him to voice his opinion solely through his anonymous vote is disingenuous and does a disservice to us, the Foundation's members, who'd like to make better-informed decisions.
Attempts to silence Murray's negative comments while implicitly condoning his and others' public endorsements reeks of hypocrisy. Disagree with Murray's language if you'd like to. Disagree with his diagnosis if you'd like to. But Murray's content (and any response from Jeff) is the "chocolate" that all of us should be considering when we vote for the next board. Jeff has the capacity to respond to Murray's critique if he'd like to. Let's let them speak.
