Or is Dalton complaining publicly now in the hopes that Facebook will pay him more later than they would have if he'd just gone along with their proposal now?
(Honestly curious: I do not have an opinion yet.)
Whether or not he is right, I'll give him a lot of respect for sticking with his guns and turning down something so outrageously tempting that hardly anyone else has turned down ever, just to chase his dreams. Props Dalton, and whether or not you get it, you deserve congrats and success for this.
When I do think about Dalton's motivations, I think he made a very risky bet and lost, and he's probably a bit angry with himself as much as he is with anyone else. Nothing wrong with that, I'd probably feel the same way.
