@jack It's like fights in hockey. It's just how it's played, there's not much you can do to stop it, and it works for both sides, so it's fair. I think once the stakes are high enough, any game is played in a way that seems degenerate to casual players. So I didn't like it the first time I saw it, but what do you do? There's no way to administer perfect justice, so we have this adversarial court system, people are going to try to get around the rules because they want to win. Understandably, it's something where structural changes will always create imbalances, so once you've got something stable, you know the problems and you can tweak the edges, but big stuff will screw it all up.
Maybe she's just an idiot, maybe not, but the effect is the same: she controlled the topic for as long as Stallman humored her, and she spewed several talking points. She injected her dogma in an unexpected place, and it was almost certainly more emotionally charged than the surrounding discussion, which makes it stick in everyone's mind.
