What is their ethnicity? I just assumed they were all American citizens. My previous comment included how U.S. based attackers alleged they did something similar to openbsd's VPN libraries over a decade ago.

Suggesting a foreign government could be leaping to conclusions as well, given domestic activists with an agenda may do the same thing. A linux kernel backdoor is valuable to a lot of different interests. Hence why counter-intelligence should be involved.

However, I just looked at the names of the people involved and I don't know. Even if they were Taiwanese, that's an allied country, so I wouldn't expect it. Who were you thinking of?

With the utmost possible respect, 'criminal or counterintelligence' in no way implies the involvement of a foreign government, and trying to allege racism on such flimsy grounds is a rhetorical tactic well past it's sell-by date.
