Is that even a thing? Never ever have I heard "mobile players = women" even on the worst dumps of the internet, like 9gag. But then again, I'm not on Twitter.
The author was making some pretty clear points about how capitalism produces meaningless addictive games. Accusing author of sexism seems like a non-sequitur to me, especially as the whole comment is completely free of any gendered pronouns, e.g. "These individuals".
(Either way I think the argument that this means the article is intrinsicly sexist is definitely reaching. It seems the accusation of gatekeeping is more valid, though I think this requires a pretty uncharitable interpretation of something which is clearly aiming elsewhere)
