If companies banned Americans over the invasion of Iraq, I would have wholeheartedly supported it, especially if the majority of that company's employees were Iraqis.

Companies should have freedom to associate, and people can criticize them for it and/or switch to another service provider.

This is also why monopolies are such an underrated threat to society. They give too much power to a single, unelected person. Namecheap is in a crowded space, so I'm not worried about it in this case.
