Joe Average User, who doesn't know anything about the internet, assumes that we, the guys who built the Internet, made sure that all his communications would be secure from eavesdropping by... whoever. He also assumes that his posts are anonymous and won't come back to bite him in the ass when he's looking for a job. Neither one of these assumptions is at all true. The problem is that back when we were building it we really didn't think that many people would be using it and everyone who was using it at the time knew everyone else. Most of us stopped working on it after three or four years of endless September and the corporations who took it over really didn't have any incentive to secure it at that point.
Way I see it, we have two options, neither of which will work. We can fix this shit ourselves and wrest control of our communications back from the corporations. Except there are several projects (like Tor) which attempt to do this and those are ignored by most of the people who say that being monitored by everyone bugs them. We could also petition the corporations and governments who are behaving badly and demand that they behave better. Then we could hold our breaths and see what happens.
Which leads us to the third option, which is suck it up and live with it. Seems like most people are picking that one.
