I think you misunderstand. You're right that to him "free === good, proprietary === bad" and since his software (GNU) is one of the few platforms that really qualifies as "free" he encourages people to use it, however he's made it perfectly clear what it takes to qualify something as "free" and many many other independent developers have released software that meets this qualification.

To consider Stallman a "dictator" is simply ludicrous, the entire point of his philosophy is that once software is released to the end user, that end user has almost all the rights to do anything they please with it, The only thing they can't do is take those rights away from others.
