sure, I am sure most of the tech industry is gaming the system, but for mid level talent, or above its very hard to find people. and when you start to drill down into
some specific skillsets its gets even harder. much of the tech industry trys to find the best people. and, many of these companys are multinational so for example
if you run data centers Germany they need to be staffed by germans that handle german data. once you start forcing arcane rules you start to run into all sorts of
issues for no reason.
better, is to address the root issues instead of blanket banning, as a protectist, isolationist which never works....
