Because I'd be hugely interested in working with a "cofounder" who broadcast his unhappiness with his previous team to a public forum as a vehicle to replace them. That guy sounds like a real rock star.
He is a rock star - and one of the most dedicated people I know. From what I've seen, he's more committed to this project than anyone else who's worked on it (including me).
However the tone of your post doesn't surprise me - you probably wouldn't understand the difficult position he's in unless you've been there before.
