This makes sense. A lot of stars expect a cut of box office revenues and negotiate that in. But the negotiations happened probably prior to the pandemic and the new situation probably was unthinkable.
Also the box office in general has been destroyed recently because of the pandemic. What would have likely been $+150M opening weekends and close to $1B totals revenue (or even more) are reduced to fractions of that.
EDIT: Even worse, it was actually to be released in May 2020, thus the negotiations for salary were likely done in 2017/2018 or possibly earlier. Disney+ wasn't even announced back then.
