Uh, no. It's about having the freedom to fix, improve, or otherwise modify the software you use. Being free-as-in-beer happens to be a requirement for that, but it isn't the goal. Think about it this way: free software developers get paid to do work, instead of getting paid for having done work like proprietary software developers. You pay me to implement feature X, which is then released to the world for further improvement in the future.
