I think I get why you want to create a free-room for the commercialism. And I think you are right that it seems like that he don’t know so much about fanfic in general.

The reason for why I don’t have so much against (slightly) commercial website is that I have an utopian idea, of a site that could go on, so you could find your find fanfic stories in your fandom, 20 years after the tv-show ended. And that the site, did not have to depended on a little group of dedicated fans, who could quiet naturally lose interest in the website after some time.
