Probably some developer who's never made a game before.
Just look for the worst Wii Ware game on the service and you've probably got the guy who made the comment.
Sure it's better that nintendo seperates Retro and Regular better bit Nintendo's Retro catalogue is way better and more extensive and better by well... a lot. So to say it's going to hurt sales less is silly.
Granted I haven't really enjoyed most of the games i've played on XBLA but they do have some real gems, and it's not like I can't see how people wouldn't like the other games.
Besides you can just download the demos of the games first.
