You'll always keep running into security issues AND the need for moderation at the heart of any community. It is possible to actually solve the security issues technically, but that is likely a generation away. Until then, the fact that the servers AND the users computer are insecure lead almost inevitably to walled gardens, and avoiding innovation. Thus there will be centralized locii of control for the foreseeable future. We can't democratize the way we use the internet back into a true commons until usable secure general purpose computing becomes widely available and adopted. We had it (secure general purpose computing) in the early 1980s with floppy based computers and dialup. I thought we'd get it back by 2030, but I'm not as hopeful any more.
