From another article on this:

“There were just a lot of men in the comments on anonymous profiles being like, ‘Well Don't hate the player, hate the game,’” Barman said. “Basically proving that they are men, they're not actually non-binary, and that they very much came [to the conference] in an aggressive nature to take space.”

And according to people on Twitter and TikTok, women were literally being shoved out of place and jumped in front of in lines, and lots of these men had “he/him” on their badges as their pronouns. These were cis men being jerks.
