I'm not seeing anything preventing the web from continuing to work like you describe. What is stopping these loose collectives from publishing and discussing among themselves without outside interference? You imply that governmental neglect and bigcorp greed are to blame, but I'm not understanding how you connect those two things.

Self-publishing on the Internet is cheaper and easier than it ever was in the past. So why do people flock to Reddit, Facebook, etc? Because they are even easier and cheaper, are easier to find, and have a built in audience. But none of those facts relate to governmental regulation or lack thereof, that I can see.
