I feel it is great that commercial Addon authors should be able to list and even sell their Addons from within xf.com. A Marketplace like that, to whatever extent it will finally get implemented will benefit everyone and I agree with XF's current policy on this.
However, I logged in today and saw this and it just does not seem right. With all due respect to Floris, I mean what is the necessity of posting it on xf.com if you don't allow people to download it, (subsequent versions), don't give support here and what irked me the most was that you don't even allow people to reply to that thread by asking Mods to close it! And the post has like a gazillion links back to the author's site.
This I believe surely goes over any justification of fair use. And yes, let me mention that I too have a Mod here which includes my sitename in title and has a link back but the link is only for the purpose of a Demo.
Anyways, maybe it's just me....
