> My very first boss that I believe is an undiagnosed psychopath is now director level over there. That told me everything I needed to know about any possible direction of the company. I no longer use anything made by them and actively steer everyone I know away to alternatives.

I had a boss who was a manager at one of Google's flagship products, and he made it his point to not let anyone forget it. He pushed people to work nights and weekends, he berated team members and threatened firing them during daily meetings, he overrode engineer's calls to not release a product to claim he released it before schedule, he threatened the same engineers if anything went wrong during the illadvisable release, etc.

He was since hired as a VP of engineering of another global company.
