Maybe this makes more sense as a change to trademark law than a license thing. If a name OpenSourceProject has gotten popular due to being open source then I would say it's in the interest of the public to ensure that OpenSourceProject keeps referring to an open source project an isn't misappropriated for something else. It's a kind of bait and switch fraud that I think should be generally illegal. On the other hand I don't see why we should care about the creator not being allowed to re-license his own work as long as no one has been mislead about what they are getting.
