So he is supposed to chuck all his hard work and walk away? This "company" has no actual assets of any sort (users, contracts, relationships, press, brand recognition, ...), except for the code, which his co-founder does have a legitimate claim to. And due to the founder dynamics, the company will never amount to anything. So these guys are basically fighting over 10% of nothing. Yup, walking away seems like the best course of action.
