From an article published last month seems that with or without Elon a lot of people were still getting fired.

Twitter as a public company was a money pit. Now is Elon's money pit.

Twitter as a public company was a money pit. Now is Elon's money pit.
Musk's purchase, as you may know, increased Twitter's interest burden, so now Twitter is losing $4mil/day.
In the absence of Musk holding the company hostage from April to November, yes, of course Twitter would have to make some cuts like so many others who've had a drop in revenue.
But there's no reason to believe they would have cut the estimated 50-55% that Elon has.
edit: And now there's impact of this decision: of those who didn't get cut, how many will decide this isn't a healthy environment to work in?
