Nothing in there states he's wrong simply he is interpreting things differently and his interpretation does not align with yours.
Also, complex but I doubt you are in the business of making games so I'm confident he probably has additional context forming his viewpoint which you do not.
Again, god forbid people have opinions. Is this where we are in the terms of discourse now? We are not allowed to disagree because one side feels they are "right"?
Fyi I have no skin in the game.
