For her career, this whole thing has been a disaster, but she is very unlikely to lose this case against Depp.
Think about what the article is saying.
1) she is a public figure representing domestic violence
2) Hollywood sided with her abuser
3) she spoke out about sexual violence
1) she is by implication saying that she is a victim and Depp is the perpetrator and that it was sustained enough or serious enough to merit public comment
2) since both were continuing to have careers (she was more successful than she'd ever been and published it in her first major studio film with an important role) she was complaining that Depp was still finding work, especially more reasonable an interpretation since it was the height of me too.
3) she republished that she was the victim of sexual violence, which is rape or sexual assault or battery
I don't think a reasonable reading of the article with an implementation instruction sustains a 'one occasion of being yelled at' or even a mutual abuse defence, though if it was proven mutual serious physical abuse no jury would decide against her, I don't think.
