> Layoffs at Google didn't happen because they had to happen. They happened because the leadership was concerned that in the good years, the company accumulated way too much dead weight - pointless projects, underperforming employees that the managers never had to deal with because they could always hire more people, etc.

This doesn't really match the reality of the layoffs. They weren't team/project based or performance based, they were seemingly random. If they were concernee about too many low performing products and employees they went about it in completely the wrong way.
