I have seen this style work really well when it is practiced in a safe environment. By “safe”, I mean everyone is striving for transparency, you don’t shoot the messenger, and you support each other (not back stab).
This can go off the rails quickly if it collides with other groups that are not as safe and have serious issues. In these more common environments, successful people learn the delicate balance of what to say, what not to say, and what order to say it in.
