The thing is this FBI purge is for the most part just pure bullshit, the same bullshit that was used to "justify" the kidnapping and hostage holding of Huawei CFO...
And the FBI purge has been going on for a long time, see previous bullshit purges
This is a double edge sword, if America continues to indiscriminately purge ethnic Chinese (even those that are US citizens, whom have done nothing wrong) and create in effect the culture and norm of a red scare 2.0 and new Chinese Exclusion Act, the Chinese government needs to capitalize on this and make efforts to highlight Amerikkka Cultural Revolution and the FBI purge quotas so as to both warn dispora abroad and to deter talented Chinese from choosing to take their skills to Amerikkka...
I get it the US intent is to prevent China from continuing to close the gap... But it they continue to go about this stupidly, this could actually turn out to be a net boon to China if play cards right... they are running scared because China is catching up not because of Chinese spying... these racists supremacists cannot fathom how a bunch of chinamen can ever catch up and surpass them if it were not for wholesale theft and cheating. This is the real crux of the matter, not spying allegations. None of the highly publicized FBI purges have been about catching real spies, and if US was purging real Chinese spies, it wouldnt make it in the news... certainly not in this fashion...
Lets put it this way, Amerikkka tech preeminence is nothing without foreign talent, brain drain and hard working Chinese researchers and scientists... let them decouple and see who net gains in the long term... I know which way this wind blows
