Marvel Studios Drops Jonathan Majors Following Guilty Verdict for Harassment and Assault

That depends, what did she say immediately before the threat?

As I am aware this came all up during their divorce and child custody case. As I am aware, they are now sharing custody. (https://www.thethings.com/how-often-does-jeremy-renner-see-daughter-ava-after-sonni-pacheco-divorce/) And yes, the allegations were very severe, but if he is allowed to see his kid, the judge must not found him absolute guilty in the allegations. So that's why he is still employed with Disney, as Disney still had Majors under contract until he found guilty.
Also during the hot phase of their divorce, Disney had not employed him (at least big). Hawkeye show was luckily planned for Fall 2021 all the time and filmed in late 2020, so they could have still cancelled it. His appearance in Black Widow, a scene heavily teased before, was so unimportant in the movie, like it could have been easily cut out. The teasing before that in the Avengers movie sounded much more like him being a bigger part.

Jeremy Renner did not threaten to kill his rx wife. Sonny Pachio is a known liar who attempted to say jer child with Renner was not Renner's. She claimed in several court filings that Renner abused her. Those filings were systematically tied to his various film releases. She claimed he sexually abused their daughter. Child psychiatrists interviewed Ava and found Pachio to have concocted the lies to win in a custody case. She also claimed Renner was an "abuser of hard-core drugs." Insurance medical exams he had to undergo in order to do the Marvel films proved he did not. Further he submitted himself to six months worth of drug testing and submitted everything to the court. On his dime, not the court's. Pachio refused to submit to drug testing and was going to be charged with perjury when she dropped all those claims. Renner has physical custody of Ava with Pachio getting visitation.

It should be noted after Renner's snowplough accident, he refused all hard-core pain meds and chosenon addictive ones, plus he also does meditation and other workouts including time in a hyperbaric chamber to promote healing. So please.
