This feels overly cynical. My long-time friend took a job at Meta (over equally compelling financial alternatives) because the manager pitched the team and growth prospects well. (Meta turned out to be quite disappointing on these fronts. I never heard money as an important factor for joining or for leaving.)

In general, the kind of people who get an offer from any particular big tech company probably can get similar money elsewhere, so it's unlikely to be as big a factor as you suggest.
