Well your dad and friends aren't sea turtles, are they? They're a bunch of selfish pricks. Sea turtles are Chinese who have decided to go back home.
I don't get why it's so hard for you to understand that a person of X ethnicity has a greater chance to be loyal to country X than a person of Y ethnicity. Does that make it clearer for you? No?
Then list some reasons that a Sea turtle would have to be loyal to China. I'll do it for you: because when China shines, all Chinese people shine; because this is truly bringing honor to the family; because this is showing all those racist schmucks that China can out-innovate them all. Now list all the reasons a completely foreigner has to be loyal to China, and I mean loyal, as in, a desire to see China rise above all other nations including their own. Go ahead, list 'em.
An American who stays in China after the Korean war is loyal to China? Are we having this problem because you don't understand what loyalty means? Do you have loyalty confused with enjoying a place?? If another conflict broke out between China and the USA, which country would these Americans want to see victorious? I have never met a Chinese person in the US who would hope that China would lose in a conflict against the US (well, there was one Falun fool but I stopped speaking to him the second I found that out). They might enjoy living in America but their loyalty is to China. They simply lack either the courage, ability or both, to go back and contribute to China. An American might enjoy living in China, but his loyalty is to the US. Get the definition of loyalty straight, and don't mix it up with the words, courage, ability, or enjoyment.
Intel and AMD can't judge on ethnicity because one, that's illegal, and two, then they'd have no talent to pick from. If an Indian or foreign engineer wanted to work for China, we should not outright reject him, but he must not be in a position of power and he must be supervised, otherwise you shouldn't be surprised if he either transfers data back to his home country or sells Chinese data to those willing to pay. Foreigners can have their use; I never said to reject all of them, but there are significant trust issues that need to be mitigated.
The point is, the talent recruitment drive should mainly target ethnic Chinese because of all the races in the world, the Chinese have the greatest reason to be loyal to China. It's not a rocket science revelation level statement. The only way you could disagree is if you were to argue that every ethnicity in the world has an equal chance of being loyal to China.
