Sanctioning won’t do anything. These former ASML employees know that their professional careers in the western world are finished. I bet they know when they are signing that they are going to stay in China or countries friendly with China for the rest of their lives.
Who is "the west" in your eyes? I personally know plenty of people in the USA who are openly cheering for Russia in the conflict. So I don't think we could say that "the west" is mad at Russia. Certain people in western countries are, but plenty are quite happy with Russia and wish them well in their endeavors.
