Concerns on privacy, data and IP are understandable. However, this ban would be a symbolic move with absolutley zero substance. The world is small and highly interconnected and it would be extremely easy for the Russian and Chinese governments to compromise and co-opt support staff from pretty much any country of their chosing. This will lulll your customers and your infosec teams into a false sense of security. Considering how forthcoming you are with the names, roles and location of your team. They would pick you off in a heart beat and you would not suspect or see it coming. The Chinese are extremely well entrenched across the global - with enough money to grease anybody's wheels. Not to mention it would be trivial for them to get their "agents" passports from anywhere in the world
