That's true...if only new computers shipped without an operating system, and operating systems didn't come with a browser installed, and you had to turn on every feature in every application or website that you signed up for. If only the world was "off" by default and I had to spend lots of time and energy trying to get things into a usable state, instead of having the settings set to usable levels by default.
You might disagree with the defaults they've chosen, but having everything "off" by default isn't a great world.
