This is standard Silicon Valley practice: Change jobs to get a better title/better pay, new company new challenge, grass is always greener... The big difference now is the pay jump. Silicon Valley salaries have jumped significantly during the pandemic. We have a serious talent shortage, much more serious that then chip shortage, absolutely.
This guy has jumped before so it should not come as a surprise. At least he knows what he is getting into.
