If so, then the law essentially forces you to give your files up and no server location will protect you.
For any person who is not being forced into giving their keys up, encrypting their own files must be safer than hoping a cloud provider won't freely hand them over to the US government.
Fine. If you're foreign, encrypt your files and store them anywhere you like. If you're a US citizen, do the same and know that the government only has them when they force you to hand the keys over.
(Barring them being able to hack them some other way, e.g. simply grabbing your keys off your machine.)
