>"Their survival is not at stake."

What do you base that on? As others have pointed out, DoorDash is losing money every quarter. These companies have experienced hyper growth in employee count while the economy is good. But they are still losing a lot of money every quarter. When the economy turns, that high burn rate quickly becomes a threat to their continued existence. I think most of these layoffs are essential and may still prove inadequate. DoorDash for instance is selling a non-essential service. When the economy tightens up, people stop spending on things like DoorDash.
