@MoeBritannica @DrRyanSkelton and that is only if you decide to contribute AFTER the change, if you contributed before, that he did means that regardless of how much code you put in the program if you want to roll out your own fork you cannot use code from AFTER he changed license, but it gets worse because you gave code in the good will that the program would remain GPL, him changing that license is pretty much stabbing you in the back as now he can do whatever he wants with your code, including selling the program and give you nothing.
