nah i think its about people not liking weird degenerate obsessive parasocial fans that treat esports players as idols. sure they can be profitable but they also damage the image of the esport and the community. could also damage the competitiveness of the esport when orgs realise they dont have to try to win, they'll just make their money from a super popular player (like 2022 sen shroud, altough an entirely different fan base).
i think we all can also agree that its repulsive as fuck when people draw pregnant "fanart" of players, and talk about them as babies and shit. that alone should be a valid reason to hate them.
idol culture is cancer, even more so when people start idolising esports players (antisocial geeks that spend more time in game than outdoors, never had jobs, dropped out of scool etc.)
