well, a co-founder was pressured or embarrassed into resigning, no? that's not a lawsuit, sure, or even a firing, but it's certainly a big deal.
Certainly, if it was a case of the guy getting pressured to leave, one could make the case that the company recognized that they had a problem and tried to get rid of said problem in the way that was least likely to get them sued, by asking someone to resign. And really, if you are an executive, and are asked to resign, what are you gonna do? You're gonna resign, and try to make it seem like a voluntary thing. Even if everyone knows you actually got your ass fired, it shows that you are the sort of executive who will play the game and not take down the rest of the company if you get in trouble.
