So it's okay to not tell the world about the exploit in the first place ? If Apple posted this against Google you wouldn't say a word. You'd just be happy for Google to get bad press no matter what they do. This post made the world's iOS devices more secure. Have fun countering that in your head with "but but HN says Google is bad..."
If you want to discuss the exploit itself, that's great.
If you are going to bring how it is targeted into the discussion, there is simply no excuse for leaving out the fact that this is a narrowly targeted attack from a nation state adversary who is also actively targeting your own devices.
I don't know if their motivation was to harm a competitor or to avoid annoying China while you are hoping to resume doing business there, but they certainly left themselves open to both interpretations.
If you don't intend to tell the truth, then it's better avoid bringing up the topic altogether.
