I agree entirely. Those of us old enough to have experienced those dreams are naturally going to mourn the loss of the Internet as a place for wild experimentation because we know so much good came from it and there isn't any true replacement.
But it's become clear that in the absence of governance, standards of behavior, and rules both explicit and implicit, the Internet has grown toward tyranny and automated exploitation rather than freedom.
We need to set some rules and expectations that people can rely on, otherwise rules will continue to be imposed on us.
