You might have misread the issue at hand, this is not discriminating on country of birth, but country of residence. You can choose not to continue living in the above mentioned countries, and this would no longer be a problem it seems.
Ultimately it affects the developers who are born in China and Russia as well. Not everyone can afford migrating to a "white listed" country due to various reasons like family, friends and other commitments.
How is that different from any other job? Unless they support remote work, which most don't, is it not discrimination for a job to only consider people who are willing to move to city X or country Y?
