Again, these are not the "smoking gun" examples you make them out to be. Item [3] in particular is a widely accepted opinion - you will find it expressed enthusiastically by such "tankies" as Bill Gates [0] and The Economist [1].
For item [4], his opinion seems rather complex. Here he is praising a thread that condemns China's treatment of Uyghurs in no uncertain terms [2]. Here he is again mentioning the U(i/y)ghur problem and China's authoritarian surveillance state [3].
(Note that if you want to see real honest-to-god tankies, there are plenty in the replies to his tweets. It seems an outlet called Gray Media, that they cite, is also a good example of actual tankies, directly claiming the Uyghur crisis is a "Western fabrication").
It's also important to remember that there is a major difference between Israel and China speaking from a UK/US/EU journalist: our countries are generally pouring billions of dollars of direct support, and heaps of diplomatic support, for Israel. They are doing no such thing for China. So, we have a much better reason to criticize Israel compared to China: we are partly responsible for Israel's crimes; while we bear little to no responsibility for China's (with some exceptions, such as slave labour for the production of export goods, or the status of Hong Kong). We can huff and puff all we want at China, it won't budge. Israel will.
What you're doing here is similar to people complaining that Chomsky criticized the USA without criticizing the USSR as much or more. His point was simple: he lived in the USA and had some measure of say on its direction. He had no such measure of say on the USSR's behavior, so he was naturally more silent on it.

It’s also hard to argue against the statements of escapees who describe being ‘brainwashed’, as well as being tortured for speaking the Uyghur language and reciting the Qur’an."
