> for personal profit

it's not just personal profit, I mean if it's true how would you react to it? Putting aside how it would affect research, it also would make many people including such in power blame China for it. Which would be a political nightmare not just for China but also US, EU, etc.

So if any secret service has proof it was a leak you can be sue they wait until there is a major conflict with China. Like e.g. because China attacking Taiwan before the US/EU become more independent of TSMC. Through at that point of time there is also a lot of insensitive to just make up a "proof". So the public probably will never know for sure.
