This is an apples to oranges comparison.

The ticket raised on gitlab is specifically about Chinese and Russian nationals, but this would also apply to Australians (they can be compelled, legally, to build backdoors upon request of the government). If I were in charge of a non-trivial company I certainly would not hire an australian national.

This same exact argument would apply for a white person from China who has family or other assets in China, and thus has leverage that can be used against them by the current totalitarian regime.

If the US government enacted a law similar to Australia where we could be compelled to build secret backdoors, then foreign companies probably wouldn't hire an American either.

This really has little to do with race, and everything to do with risk and governments. We would still be discussing a ban on hiring Chinese nationals even if China -weren't- almost completely homogeneous in race; it's basically irrelevant.
