For a business person, it is difficult to talk about actual condition of one's company.
Evermore criticism or exposure from within are out of question.
If you use anonymous name on SNS, it is easy to specify the original because having "the information".
Once you are specified by a organization, you might have to accept your lose.
"Majority decision rule" is not an exclusive feature of "democracy".
Even if you are a very gallant person, I am afraid that you don't have network of connections, position and friends.

(Case 2)
For a business person, it is also difficult to talk about actual condition of other's company.
There is few person who knows the actual condition, and it becomes easy to specify the person.

If I am asked "a business person cannot speak anything anytime", I think that it is not so.
What you do is to leave the organization. You will not be attacked by that organization.

The conclusion is "I envy a freelancer".
