Wow. Totally absurd. Apparently you can't remove software this way either, only add it.
The comments are also pretty crazy too. David Zeuthen compares this to automounting storage devices. Hello? Automounting storage devices only happens when I am in the same room as the computer, inserting a new storage device.
