The Ruby community has been eating itself alive since almost the beginning, but it is sad to see the short-sighted destruction of trust and connection that this has had.
It's true Ruby Central was a fiasco and the maintainers should have been treated better. But the author's investigation misses important elements like the "culture war" on both sides. That seems to be prime motivation for everyone involved, given the flames raging in the comments below.
This was likely a reaction to a mix of NPM + culture war/deplatforming, where power player got nervous and decided to clamp down on rubygems security to insulate it from hypothetical bad actors.
