Conversation so far:
What was important about terminology?
Stallman places great importance on the words and labels people use to talk about the world, including the relationship between software and freedom.
So he believed software should be free?
He asks people to say free software and GNU/Linux, and to avoid the terms intellectual property and piracy (in relation to copyright).
What didn't he like the use of those terms?
Stallman argues that the term "intellectual property" is designed to confuse people, and is used to prevent intelligent discussion on the specifics of copyright, patent, trademark.

Question: What did he do to get these terms changed to something else?
Self-contained rewrite: Besides confusion, Richard Stallman did change the terms "intellectual property" and "piracy" to what else?
