The Pegasus spyware facilitates injustice on the part of repressive or corrupt governments. It is used against dissidents and investigative journalists. We would be better off if it did not exist.

Would prohibiting the sale of that program make the problem go away? Not necessarily. Users both authorized and unauthorized might continue using it.

Pegasus exploits a problem inherent in the nature of Android and iOS: they are nonfree software, so users cannot do anything to strengthen the system. Instead, they are helplessly dependent on Google or Apple.
