Many (most?) companies do. They make the tradeoff that the false negatives (those from non-targets who would be hired) are worth losing out on in favour of the smaller amount of applications to process because among that smaller pool they have a higher true positive (those from targets who do get hired). In stats/ML speak, they favour high precision [0].
We also have to understand Russia's grievances instead of seeing it in terms of an evil side attacking the good side because it's not that simple. The US would hardly be best pleased if Mexico started receiving arms from China and North Korea right at its border.
The Russophobia that has been pouring out is lamentable. And people don't realise this will only push the Russian people further towards Putin to re-establish their pride. And the sanctions are making this even worse. This mirrors Germany's treatment with the Treaty of Versailles leading up to WWII.
