>Andre has previously maintained that he owns a trademark on Bundler and he will enforce it against Ruby Central.

Well,

1. He's not fighting Ruby Central anymore, he'd be fighting the Ruby core team.

2. He's going to have a tough time asserting copyright on a name he didn't come up with on a project which shipped v1 before he joined.

3. If he believes the trademark belongs to the community, the right thing to do would be to transfer it to Ruby Core then, right?
