That's kind of the same argument for European businesses and governments to not use Microsoft/American products. At least if they did it within EU, they would be accountable, and the laws prohibit most of it. But the US spying is unaccountable to Europeans, so they can do whatever they want.

The only proper answer to that is to stop using American products (at least until the US government can prove with extreme oversight from Europeans and Latin Americans and others, that they aren't abusing their spying power anymore).
