GNU guru Richard Stallman sent me an e-mail the other day complaining that we erred by saying that the Free Software Foundation, of which he's president, promotes open source software. "We have never supported the idea of 'open source' because that idea denies the importance of users' freedom," he writes. Read on for the dizzying semantics behind Richard's argument, and why I think his obsessive attempts at language control are shooting his own software objectives in the foot.
