I would only be concerned if they removed the iconic licensing from the site all proper OS has it including Xoops, Joomla and anything else you find in "fatastico". If he has I would check his Contributor Points because every STAR is a licensed free DOLPHIN so he could have built in that to the hosting he charges.

It looks more like a poor-mans web shop which usually operates inside OS guidelines just shadows the reality of what that is... Like PHP Facebook running on a Dolphin6.0 Beta see more Script released openly last September. But by his approach he lacks the capability of upgrades.

And he is technically just Marketing his own way. No different then a DolphinGeeks might or even how DolphinDomains.net is staged. There's many way's to market open source as a company...this is his.

I prefer exposing the source rather then hiding it but that's just me :)
