This is, to some extent, precisely what happened to most of the internet. Things run for passion withered away; things run for profit remained. New people grew up surrounded by only for-profit things, and believed that was just the way things were supposed to work. They've never seen a personal website.

When I was 5 or 6 my dad helped me make a web page about the Star Wars movie I just saw and didn't really understand but I thought the pod racers were cool. Apparently our ISP came with a little bit of web space. That doesn't happen any more. You don't even get Usenet.
