"There are three kinds: those that spy on the user, those that restrict the user, and back doors. Windows has all three. Microsoft can install software changes without asking permission. Flash Player has malicious features, as do most mobile phones."
"Digital handcuffs are the most common malicious features. They restrict what you can do with the data in your own computer."
