Surely you mean "they are badmouthing". Enough to be expelled from the PSF.
Some official report from the PSF does not invalidate decades long observations. I see increasingly that programmers rely on PDFs from foundations and official statements from bureaucrats rather than look at the source code.
It is misinformation because it elides the context: white guys got virtually all the mentoring already, represented the absolute majority of core developers, held all the power in steering the language, etc.
So what he's saying is: my personal efforts focus on helping those that currently don't get help, don't have a voice. White man are doing fine already, they can forget getting direct help from me because they, as a group, don't need it.
So yeah, you can be upset that he's not offering to help those who, as a group, already have a path to getting into Python. Says a lot more about you though.
Linux people get really worked up when I say "platform-native". There is no such thing on Linux, but reasonable people agree that something like a GTK app (or Qt) feels "native" on *most desktops* over other applications.
The Python community is welcoming, many come for the language and stay for the community. It's not, of course, free of politics or drama, but it's very far from what you describe. Local communities are very strong, CPython core community seems to always be trying to improve to me.
Even Tim Peters, who I really hope is part of the documentary, is an enthusiastic participant, both helping with gnarly CPython issues and providing assistance to newbies.
If you look at the Fellows list[0], you can see that many important names aren't active in the community anymore (I don't know the reasons for each one), but many more are either active or in (very) good terms with the community.
The CoC was and is a net positive, the diversity efforts even more so. Last Saturday I was at a local Python conference and the local community has welcome both, to great success and improvement.
"There's a huge evil magnet that will tear you apart if you have any metal on you" sounds much easier to grasp and less likely to lose the listener's attention. Then, when you have them listening: "It can grab you from outside the room and hurl you into the machine where the evil magnet lives! Any metal, be it coins, necklaces, pins in your bones, belt buckles, bra wiring, dog tags. Anything can be the end of you, be damn sure you don't have any metal on you."
Oh, wait, you still want them willing to go near the machine? That complicates things a bit ;)
