How do you know they haven't profitted. Because they say so?
Anyway, they don't need to be profitting from this to be false. They may believe this all to be true, and are acting accordingly. People are known to act 'selflessly' for different causes.
A perfect example is Christendom. Many become Nuns and Monks for their faith, others become volunteers and missionarys. Do their selfless deeds mean that the Christian religion is true and valid? Nope.
The book doens't need to be disproved, as the book is making a claim but without any proof. A proofless claim can be considered useless.
Therefore if I said that my dog lays eggs yet I do not show you the dog nor the eggs there is no need to consider my claim, the claim cannot be proved without the proof so to speak. But even though you can say that dogs don't lay eggs therefore it must be false, you actualy have no way of knowing that all dogs don't lay eggs because you haven't seen them all and you can't know if this particular dog does or not. So technicaly you can't disprove a claim that is proofless.
Essentialy disproving something involves showing that the proof (evidence etc..) is false or invalid.
But here we have no proof, hence it cannot be disproved.
