I'd certainly like to see this. Why not just ask the webmaster to send a copy to us. They could easily set up a share in dropbox and share the link to anyone who requests it rather than posting it directly on the site.
I would think the webmaster is probably right: trying to make noise about this is more likely to cause WotC to reconsider the fan material program as much as anything.
