You can dislike the game, but being a martyr and refusing to play it is just giving up potential benefit for virtue signalling, and if he's trying to start a "de-Google" revolution, I would expect a more serious effort than this lone page that many normies would mistake for an error message at first glance.
I don't know about this guy, but it might not be virtue signaling. It might be that he simply doesn't want to take part in that "game". So what if he's giving up some potential benefit? Not all benefit is worth the cost.
