Quite likely right here, but my position is rather than suppress knowledge of it like the Chinese government wants, all authoritarian atrocities should be equally talked about.
But China does talk about it. A lot. There are MANY studies done, by journalists and historians, talking in details about what happened (even the student deaths).
There were even western journalists there, reporting live. Many had to publicly denounce the newspapers they wrote or reported for for manipulating and distorting the truth.
