The real analogy is that we're taking away pencils because writing in the wrong book can cause you to lose all your money and cause months of problems. And these books are disguised as your own diary, cookbooks, maps and the TV guide.
Don't get me wrong, I absolutely do not support "walled gardens" that are now becoming common and I don't think they are the solution to this problem. Power should always be left in the hands of the user, the solution is education. This is of course a social issue and one of gigantic scale. There are so many strong political hurdles to overcome that I'm not surprised that the industry has taken the approach it currently has.
