I'm sure removing these maintainers would be of great help to the Ukrainian war effort...
More seriously: We need to help Ukraine more. But this doesn't do that. It just hurts a bunch of people (both the maintainers, and the people using their code) for no benefit whatsoever.
As someone who has no knowledge of the ecosystem: Why would people who self-gost wordpress care about access to wordpress.org? Isn't the point of self-hostung to use your own infrastructure?
