I don't think you were punished for success, a lot of people use the same argument when they make too much money on PayPal and then decide to claim PayPal was in the wrong for asking where the money came from.

You're right, they don't need your business. One person not working with them won't affect them at all, sorry to sound harsh but they have millions of others.
