As an employee, I wholeheartedly agree that he should have been paid if he had some written form of agreement (email counts).
As a sensible logical person, I think he should have gotten paid when he was an employee especially since this was an employee perk.
I don't need to be a founder to know that he's not entitled to anything from the company when he's no longer an employee. What's the limit here? Can any past employee in the history of the company suddenly realize he's entitled to some perk, come back and demand it? And if he doesn't get said perk, publicly shame the company?
