New CTO instantly put the entire team on blast. Is huge on public shaming (even when asked to bring criticism privately), swears actively in meetings, and makes many people uncomfortable. He pushes the team to implement massive large-scale changes on many things for really no reason other than he has a preference for one tool/technology vs. another, even when people highlight that both tools are functionally the same. He has huge problems with very specific people, and targeted them for dismissal/role reductions which drastically reduced the diverse pool of contributors that was originally there. Quite a few people have departed now due to him reducing the diversity that existed previously, causing many employees to feel unwelcome.
