Power corrupts, so the proprietary program's developer is tempted to design the program to mistreat its users&mdash;that is, to make it malware. (Malware means software whose functioning mistreats the user.) Of course, the developer usually does not do this out of malice, but rather to put the users at a disadvantage. That does not make it any less nasty or more legitimate.
