Not exactly the same as orgs but it reminds me of the very very difficult skill of "criticizing the king". It's possible, but it requires a lot of finesse and skill, and even then you might get beheaded.
And it goes without saying, overtly criticizing the king is pretty obviously a bad idea.
I guess you are right. After that experience, I was very cautious to work for another company, because I find it very difficult to keep my mouth shut. I love to discuss how things are wrong and how I had an idea of how to improve things. Now, I am building my own company and will try to walk that walk when bringing my own employees.
