That's correct. It is often misunderstood by Western public. To complement, for example in WeChat if a lot of criticism or even much worse than criticism can exist in "Moment". But it can make a WeChat Group be banned. Another thing is there's no danger for any individual who express anti government opinion only. Too many people do it all the time. The only chance to cause trouble is when the individual is trying (or perceived by government is trying) to instigate some public demonstration. Otherwise is pretty safe.
