I agree with the basic point of the article but many of the stated facts are outdated by now. Since this article has been posted it has become much harder to bypass the firewall than it was back then.
Do you think that another danger of inconveniences is that it's easier to make an inconvenient mechanism more and more inconvenient than to start restricting something that hadn't been restricted before at all? Like having a tiny inconvenience at first somehow "reserves your right" to add more restrictions in the future?
