This is only a win for Ruby Central. They haven't conceded anything and they've convinced Ruby Core to endorse them as the correct and true maintainers of RubyGems.
> While repository ownership has moved, Ruby Central will continue to share management and governance responsibilities for RubyGems and Bundler in close collaboration with the Ruby core team.
Andre has previously maintained that he owns a trademark on Bundler and he will enforce it against Ruby Central.
So Ruby Central transfers "ownership" of Bundler to Ruby Core. Ruby Central gets to continue to maintain Bundler, and Ruby Core is stuck with the liability. If Andre wants to enforce his trademark, he now has to sue Japan-based Ruby Core and risk the bad optics of that.
