Extensions with no license
I agree with WMF taking ownership of content posted. So by that - could we then just assign GPL to any extensions that don't currently list a license?
I'm not too opposed to GPL licensing, since it's so well understood and widely accepted, but I think it might be better to make it public domain, like we're already doing for Help:Contents documentation that is meant to be planted into every MediaWiki install (if desired). Making unspecified contributions public domain by default:
- Assumes nothing.
- Imposes nothing.
- Can be changed later, if needed.
In short, if a contribution does not come with any specific licensing restrictions, there's no reason impose any. But, with that said, I think just choosing SOMETHING is better than just leaving it an orphan that everyone is afraid to use because it might turn into an intellectual property minefield.
