Companies won't do anything because money is king, most companies don't have a moral compass. It's all about profit. If she's bringing in the money they don't care, they'll turn a blind eye. Just boycott anything she is linked to.
The worst of it all is her smugness. If she'd come out and said, " I made the wrong decision, in hindsight I should of stayed home and I am truly sorry", people would move on. She's giving anyone that has a problem with what she did the two fingers amd two fingers to all those doingvtheir best to keep others safe and to all hralthcare workers, that's nearly worse in my opinion.
Most "influencers" are narcissists, she seems to fit the bill here too.
I genuinely believe in karma, it may take awhile but everybody gets theirs.
