There was a time when I questioned decisions like Amazon hiring[1] 50k tech workers along with Google, FB and other tech giants, because I did not understand their value to the company, when it seemed like they do not absolutely 'need' that level of tech workers.

Now I think I do:

1. Those engineers will less likely to upend the apple cart by inventing something that could disrupt business 2. Those engineers will be kept away from competition, where they could do something to help competition

Those tech workers are sufficiently happy that leaving is typically not an optimal choice.

FWIW, I am just typing aloud. So please correct me if you see a flaw in that reasoning.

Denying your competition human resources you don't really need yourself is a strategy I've seen in real life. Can't comment on the other points.
