Their resignation is already being discussed in another post here from yesterday: One Of The Rust Linux Kernel Maintainers Steps Down - Cites “Nontechnical Nonsense”
…but I think this LWN reporting (from back in June) deserves its own post as it makes it easier for those of us who are not kernel hackers to follow what is going on.
I find it a bit worse as it is basically “there are more of us so you do mot matter and that is not changing anytime soon”. That is about as far from a technical argument as you can get. It is also basically bullying.
That’s a very good assessment, I think. I was being a bit overly charitable, perhaps.
