Private enterprise is what made Internet the way it is today. However with annoying things like banner ads and porn, it lets you have things like E2 and slashdot. In many cases it's this private companies that pushed the technology into your home (and the home of some shmuck who thinks that his homepage interests anyone).

Take TV for example -with 3/4 of it being ads and pure crap, the other 1/4 is sometimes genuinely entertaining and even educational. What I am trying to say is: with masses comes crap. But it doesn't mean that the good old stuff goes away.
