Google is cutting a few hundred R&D jobs out of their 180K employees, and countless ventures. These people could be repositioned, these people could be absorbed elsewhere. Google is wildly profitable, with record profits, which by definition means what they’re not falling on hard times.
Loyalty is dead.
Something that has never existed cannot die.
But the myth, and the brainwashing, of "employee loyalty" is still very much alive. Some even buy that crap.
There is absolutely still some loyalty in the other direction. Lots of people here would say it's misplaced. When it works out for you (cachet in the org, seniority, whatever) it can pay off, but for lots of people it only gets them burned when they get laid off with outdated skills in outdated tech because they were a "company man" for the last decade.
