Look, I just want to be done with this, so let me lay it all out as I see it, starting from the beginning of where things went off the rails between myself and Michal: Michal's (as well as Steve's) behaviour in the memory allocation profiling review process was, in my view, unacceptable (this included such things as crashing our LSF presentation with ideas they'd come up with that morning, and persistent dismissive axegrinding on the list). The project was nearly killed because of his inability to listen to the reasons for a design and being stubbornly stuck on his right to be heard as the maintainer. In my view, being a good maintainer has a lot more to do with stewardship and leadership, than stubbornly insisting for - whatever that was. In any event, that was where I came to the conclusion "I just cannot work that guy". Next up, PF_MEMALLOC_NORECLAIM over Michal's nack - I was wrong there, I only did it because it really seemed to me that Michal was axe grinding against _anything_ I was posting, but I still shouldn't have and that was more serious infraction in my view; that sort of thing causes a real loss of trust, and no I will not do it again. The subsequent PF_MEMALLOC_NORECLAIM discussion was such a trainwreck that I don't think I will go into it. Except to say that yes, if it makes you happy, I shouldn't have used that language and I won't do it again. But I do have to call out you, the CoC board's behaviour, and I think that ony fair since you call out other people's behaviour publically. Greg's behaviour when he approached me at Plumbers was beyond unprofessional, and since it wasn't exactly public and you guys have already heard about it privately I won't repeat exactly what happened, but it is an issue. Shuah, you weren't much better. There were concerns raised in the recent CoC enforcement thread, by someone with experience in such matters, that your aproach seemed extremeely heavy handed and I find myself in 100% agreement. The approach you take is that of a bad HR department: all about image, no understanding. When tensions arise, it's important get to the bottom of things, to at least try to take the time to listen with an open mind. People have real frustrations, and it's amazing what you can learn and what you can accomplish by having real conversations. But that's not what you guys do: you say "Ok, if someone's being too much of an asshole, we'll just be an even bigger asshole!". No. Cut that out. I've done the hard work of stepping in and building bridges when relations have broken down (on quite a large scale), so I'm offended by what you guys do.
