yeah, that imbalance would be the problem... but it seems like there would be a variety of ways to combat it... the internet is an almost free way to get information about a little known product out... I mean, the more in-your-face the ads, the more they cost; it costs money to put pop-ups on a trillion web sites, but it costs next to nothing to have your own web page up a googleable, so there's at least a certain minimum exposure that nearly everyone has access to...

In searching for solutions, my focus would be on increasing the ability of small players to get information out, rather than on limiting or censoring the big players...
