Without Stallman and the GNU, we would still have just as much software on the market. Many of the people and companies would have most likely released it under the BSD license (or public domain).
..and like I said. I still don't buy it. Piracy causes unknown amounts of damage to commercial software companies. If the community comes to terms with this, I might be more apt to come to terms with the amount of unknown "good" Stallman has done.
