The Product team changed leadership in early 2016. Since then 10 members of the PM team (8 PMs, 1 UX and 1 Docs) have left, and 5 key engineering leaders have left. All mostly because of the CPO. He publicly humiliates people, berates them, and mocks people and teams in their absence. He refuses to listen and tries to play the 'alpha male' in which he seems to have the best opinions and answers. I have personally witnessed the culture shift in the PM organization, and am very sad to say it's going to take the company down if not addressed.
