I like Hindering Backchannels Rule. Thank you for ceasing to pay homage to a non-free culture production. I suggest only keeping rules 2 and 3. The others are persnickety and do not HB.

On the whether 3 is "enforceable": the only invocations of HBR I've ever seen have been Fontana and (mostly) Kuhn complying voluntarily. Perhaps change Rule to Norm.

As to whether 3 grants leaders control of a project's narrative, perhaps it does, but if you want to view ironically, I'd say HB "cures" give participants the opportunity to tout their self-importance and insider status. Selecting for this sort of insider seems preferable to selecting for backroom dealing, but perhaps that is an old fashioned (pre-2016?) evaluation.

I was curious whether GPLv3 makes the cut in Harvey's firm bio. It does, under "credentials" rather than "experience".
