I'll offer a slightly different opinion. If they're really good guys, charitable, nice, community oriented, then it would be cool to see them succeed.
Which they won't if someone doesn't decide to be dead honest with them about their beer. If there's something as simple as stuff that most of us already know (yeast pitching rates, cleanliness, fermentation temperatures) then they are doomed to fail if someone doesn't set them straight, now. A failure of a brewery might let someone else get cheep equipment down the line but I don't think it really helps the craft beer cause very much.
