> Let's get this straight: he's not on a soap box (a term that refers to people who shout at passers by on the street), but rather at a conference at which he was invited to speak. The audience came into the room to hear him give his talk. Lennart rudely interrupted this.

I was actually there and the talk was so much better for this. Also, I don't think the Chaos Communication Congress is that much like a business conference. It is hackers and people who care about software, not so much for proper manners.

If I remember correctly, Lennart specifically came to the congress because there were rumors before that this talk will be bashing Lennarts software, so it was no surprise to see him show up.
