men are in "competition". women only want the best men and if a man gives up and becomes trans they do not mind, since they do not have to bother with him anymore. now if a man was to increase his masculinity he would cheat the competition for women and as such they do not want that.
it is similiar to how some men complain about male up. except shitting on men for tryinf to become more attractive via unnatural means is socially more accepted.
