TL;DR: limiting freedom of expression in name of national security, without a just trial. Stretching a bit, we call it the freedom from fear (of unjust prosecution), which is the—arguably justified—distrust of the rule by law in China (not the rule of law that Hong Kong previously had). Note that Hong Kong people are using “Freedom from Fear” [1] differently from how US is using it [2]. Chinese courts work very differently from Hong Kong ones: they swing with politics. Many people have been—as perceived by Hong Kongers—unjustly detained or prosecuted (such as the milk powder incidents [3], the two Canadians in China after the Huawei case [4], or the more recent whistleblower Li Wenliang). And those people, in some cases, are sued for charges such as spying or subversion, which is the main theme of the national security law. Given that Chinese agents extracted Hong Kongers in the Causeway Bay Books disappearances [5], Hong Kongers fear that the new national security law (which allows state agents to police Hong Kong [6]) means that Hong Kongers (and perhaps foreigners) may face state agents extraction from Hong Kong. To many Hong Kongers, voicing out for social injustice could mean instability in China, and could mean theft of state secret or subversion as CCP see it. Hence it is limiting freedom of speech.
