This is exactly the point I was going to make. I have no doubt Twitter and most companies could be run in maintenance mode with 20% of the current staff. However figuring out which 20% is the tricky part. Typically I only need 20% of the lights in my house to do what I need, but that doesn't mean it's a good idea for Elon Musk to come into my house and just randomly remove 80% of my lightbulbs. To successfully pull off such a major change in staffing in such a short window would require knowing the ins and outs of the company extremely well.
