This is very true. People are getting very caught up on discrimination without taking into account all of the "acceptable" forms that happen all the time. If you're a violent felon, you are likely going to be discriminated against when looking for a job in child-care. Yeah, this is an extreme example, but it's a form of job discrimination most people see as reasonable. Like-wise, people are discriminated against all the time in jobs for things like lack of qualification or lack of relevant degrees, etc., and again most see this kind of discrimination as reasonable. The kinds of discrimination that aren't reasonable are things like no hiring somebody because of their race because there isn't any reasonable connection between that fact and their ability to do job.
The question here isn't whether it is discrimination to not hire those who live in Russia or China, the question is if the underlying premise that those people are more of a data liability than other people. I haven't read the entire thread, but so far I haven't really seen much discussion on this point, just lots of people saying the policy is outright racist (even though I believe the policy only affects people who currently live in those countries regardless of race rather than not hiring people of Chinese/Russian descent who live elsewhere).
