I would if that's what all, or even most, instances of modern political correctness were. It's also telling that the person trying to bully him into the change definitely did not treat him with dignity, by falsely accusing him of being a fascist when his family suffered and died at the hands of fascists and when his own views are the opposite. Computer code can't literally enslave other computer code (at least not until AI improves by a lot). Inanimate objects can't cause or experience suffering to/from other inanimate objects. Abstract concepts don't have agency. A master-slave relationship is just an accurate and abstract way of describing certain kinds of concepts.
