One of the things about this that is most tragic is that Hong Kong used to host vibrant, large Tiananmen commemorations in physical spaces. One of the first things an "expanded definition" of national security has been focused on is social media content related to 6/4 in Hong Kong - a total 180 degree turn. As a result, it now appears that Hong Kong has gone from hosting thousands of people in the open to talk about June 4th to criminalizing social media posts about it. Indeed, a dark turn.
