You’re not wrong. I just think that if you believe there is a good chance of having legal problems for your project (I don’t see why they wouldn’t have thought that), then it makes the most sense to do it anonymously from the beginning to avoid getting sued. Yes they can still possibly offer you money, but it might not be worth revealing your identity at that point either, as any continued development could be assumed to be you, and then you must defend yourself in court if they sue, even if it was never you.
