Being technically legally allowed to do something, doesn't make someone any less of a complete asshole for doing it, nor should it exonerate them from being called out and shamed for it. He's free to be a total dickhead, I'm free to say that he is one.
I wonder what else this jagoff could have used his skills to develop, instead of coming up with a way to get paid to be an incredibly massive tool and enable others to be incredibly massive tools.
