I'm not a fan of Kyrgios...however he was reacting to a fan who was not being controlled by the stewards. He made a complaint based on the information available to him at that time and based on his perception of the behaviour of who he thought was the cause of the disruption.
He didn't state any facts, he said "looks like". That's his perception when he was trying to concentrate on the game so naturally his complete focus wasn't on the person he perceived as causing a problem.
Given that he can easily afford either an excellent legal team who will tear this to shreds or a substantial fine it'd be interesting to see what his response will be given his personality and own personal battles which he hasn't been shy about admitting to.
He may just double down, confirm that was his perception at the time and make a huge donation to a charity that supports alcoholics whilst fighting litigation just to make a point. He may roll over and apologise unlikely and settle with the woman who is determined to get attention whilst asking for proof of the donation to charity.
Either way it'll be interesting to see what happens next. Why you'd poke a stick at a knowingly volatile wealthy person I can't imagine unless she can prove defamation and it has adversely affected her earning potential and wellbeing.
