It was "just" an offer with a large premium over the current stock price.
So I suppose if you were sitting on 300k in equity it was now worth 480k, but it's not like going from illiquid paper wealth to a liquidity event...and given the company's growth trajectory it seemed likely at the time that it would get there in a year or two on its own, without a (risky) acquisition.
Dunno, doesn't seem like a slam-dunk case of F-you money to me.
Exits are for founders / top-level guys.
They didn't do it for the personal money, they did it because they thought their shareholders would sue them, at least in part, for turning out a deal that was too good to be true.
Note that I'm not saying that others who don't avoid those things are wrong -- they're not at all. They just have different business goals and priorities than I.
