This is a broken management style, carried out by people who have no training in managing company culture or people in general. It's the same broken idea that Basecamp implemented. There's nothing wrong with wanting a certain culture within your company. It's healthy to have a shared vision, and shared idea of how you should behave and present yourself. It gives people a sense of belonging and a community around their work. That culture needs to be implemented with actions, and by the leadership behaving according to that culture, not by sending out a memo. If the problem is that some people are aggressively pushing a certain politic or behaviour not tolerated by the company, then you deal with those individuals directly. Trying to manage by memo is like being back in school when your teacher would complain endlessly about those students who doesn't show up. You just end up sitting there an wonder: "Is he complaining about my behaviour? Am I suppose to do something?" and then you get angry, because you have to listen to someone going of about something you have no control over. Sadly a tendency to avoid interaction with "assholes" and just blasting out a message and expecting the assholes to understand that they are the target of the message. It's not working and it provoking the rest of us, pushing us to a point where we stop careering.
