I think one important thing for people on HN here is this:
> I think Carl, with his background as a Corporate Finance guy, seeing the world through that filter, must have believed that I was trying to blackmail them; trying to maximise my revenue, like the “rational agents” that populate economics textbooks; that I was refusing to sign it to hold up the deal, because I wanted to get paid off. And I totally get how he could see it that way, given where he was coming from; but that wasn’t really what the issue was.
There are many people on HN (and elsewhere) who see behaving as a rational economic actor as a default state and - worse - many believe economics is a zero sum game.
Neither of these things is true, and it's a big mistake to think so. People do things for diverse motivations, and money is only one.
