Think this is only one side of the story though, what about people who had worked there just doing their job and you're being told there is something wrong with your culture and this person is being brought in to fix it.

It's a big company the whole thing can't just be a frat house there must at least be some percentage of decent people trying to do a job that are now being told there is something wrong with them.

(Not to mention the whole idea of a remote worker involved in any sort of culture change is utterly absurd)
