"If you want to know who rules over you, just look for who you are not allowed to criticize"

What is wrong with this statement? Geniune question.

In China you are not allowed to criticize the central government.

In north korea, you are not allowed to criticize the Kim Jong Un government.

In South Korea you were not allowed to criticize KMT during the 40 year dictatorship backed by the US.

In the US and Germany, you lose your job or funding or get kicked out of uni or lose your Visa or get jailed if you criticize Netanyahu or Israel.

Someone please explain what is wrong with this statement, it's a genuine question.
