It will only rot if nobody wants to work on it. If Eclipse is horribly bureaucratic, then developers who don't want to participate in an Eclipse project may now fork it. Seems like it's a win-win. If there's a group that can't abide whatever constraints exist with Eclipse, then they can fork. If not, it's still better off being open than not. I don't really see a downside here.
