I was thinking about it recently. For Linux to compete with Windows in corporate settings it has to offer some very specific functionalities. It has to basically be remotely managed. At one of my previous companies Mac users were not able to use AirDrop or even change the desktop background and screen saver. Linux users still had root level access and could do whatever they wanted because the company didn't have tools to manage Linux desktops. If Canonical is trying to get corporate clients (and I think they are) then yes, they absolutely need to treat their users as if they can't be trusted. That's because corporations don't trust their employees. And it's perfectly fine, just don't use Ubuntu as a personal distro.
