I was at Amazon for 8 years, left in January of this year. VP I worked for routinely belittled very senior engineers, made some of them cry/move teams/quit. The VP was never disciplined or had his scope reduced.

Had projects cancelled on a whim without an actual replacement/reason.

At Amazon, I wasn't a person, but some resource.

Some orgs were fine, most are not.

A manager from a "no jerk policy" org told me there is a culture of cruelty in Amazon management, and if he played the game he would have been at a higher level.

ymmv.
