Here in the UK it varies between unwise for commercial businesses to use US data storage through against internal rules for many government organisations to straight illegal for anything that has personal information like hospitals and police.
The US is now an inherently untrustworthy nation as far as data and technology goes.
You can't say it's your right to spy on everybody and then be surprised when the rest of the world tells you to piss off.
I should think US firms would be becoming pariahs around the world -- because the only rational thing you can do is to assume that any US company which has access to your data is being forced to spy on you. Because, they pretty much are.
The amazing thing is Americans might start to act like whiny bitches who say "but that's not fair to stop buying our stuff because we're spying on you", and wouldn't understand why there is no way they can be trusted.
So, congratulations, America. You've shot yourselves in the foot. And all of a sudden no sane person outside of the US can trust you with data. Don't act all surprised.
At some point, I'm expecting some aggressive whining about trade agreements to try to force people to buy products which will spy on them as the government throws a tantrum protesting the logical outcomes of their own policy.
Having billions of dollars in exports disappear is pretty much what the US should expect.
