Who’s to designate what is a tyrant and what is not? Looking at the USA, it’s sort of hard to tell.
China earned that the status of tyrant (and continues to earn) since June 1989. The lowest point of the US has yet to even come close to reaching the high point of the PRC (and the PRC's allies).
We could consider ourselves fortunate that China is so obsessed with domestic riches, earned by traiding. When it goes to grab the riches of others by force (a la Putin) ... THEN we have a legitimate problem.
Given that they deal with despotic-leaning countries, arbitrarily prosecute/kill people they don't like, commit unchecked economic espionage, enforce disappearances of people and information, actively turn countries away from freedom (Taiwan and HK), deny the majority the ability to participate in prosperity through internal immigration control, deny unrestricted practice of religion, and otherwise turn away from freedom - China deserves no such praise. The lone positive is outweighed by too many negatives.
Now if you were referring to Taiwan (or even Hong Kong SAR), a lot of those disappear. They either are friendly with the US or maintain some degree of freedom not experienced in China.
To make sure two specific points are not misinterpreted:
Religion:
I’m specifically calling out their persecution of Christianity.
Freedom(of all varieties):
They’re turning Taiwan and Hong Kong away from freedom towards PRC-driven control.
