Is your contention that Hong Kong is also a totalitarian society? Have you been to Hong Kong in the last 5 years? I feel like people saying these sorts of things are just completely divorced from reality.

No. There were a few incidents very early on, when everyone was (quite understandably) panicking about a new, deadly virus that nobody had ever seen before, when some local city officials barred the doors of people who had just come from Wuhan. That was a scandal inside China, and it was immediately reversed.
What China did do quite extensively was border quarantine, and during localized outbreaks (caused by cases that slipped through quarantine at the border), mass testing and quarantine measures. This was during a once-in-a-generation pandemic that killed millions of people. In China, these measures saved several million lives. The estimates are that China's overall death rate was about 25% that of the US, and these measures are the reason. By the way, Taiwan and Australia took nearly identical measures, and I very much doubt that you would call them totalitarian societies.
