If the attitude of the author is "invitation only", then you don't get the luxury of choice if you're not invited - that particular attitude trumps any quality argument.
Edit: I'm not really familiar with the particular politics here, but attitude of authors is not a trivial thing. Similarly, the wealth of GPL/BSD/MIT-licensed software that we all benefit from is strongly linked to the attitude of the authors.
