It paints her as a shitty girlfriend, yes. Big deal -- none of the public's business. Makes him look like a pathetic loser too though, airing his own private drama for all to see and enlisting 4chan dumbasses to harass and smear her for for it. Calling her out for allegedly sabotaging a dumb little video game project is fine if she did it, but putting her name out there and airing dirty laundry about private infidelity so that virginal internet gamer dumbasses can troll comment sections is some low level shit.
