Actually, regardless of what Matt and company might wish to see fans do to support a great property the company no longer has the rights to... in all fairness that was pretty much the only answer he could give. You can't expect others to respect your copyrights and IP if you don't do the same for others.
Respecting the copyright is why I joined this board to ask
Given that other companies have let authors release unpublished materials for licensed games after the line was canceled (obviously the companies themselves can't publish them), it seemed like a reasonable request. Not sure how they justified it, maybe it was a case of "Since we never paid for this it's not ours to say, but if you want to release it as a fan work that's between you and the IP owner"? Total speculation on my part.
While I'm mildly disappointed with the answer, I'm not at all surprised. C'est la vie
