Privacy of European computer users requires NSA vassal companies, e.g. Microsoft, to fuck off because they aren't reliable.
Microsoft isn't going to magically become reliable only because it says it cares about privacy, nor because it actually defends the privacy of USA customers (which is remotely possible after all).
Microsoft is currently in contempt of court because they're refusing to hand over data the US government wants. They're appealing. If Microsoft isn't reliable, then nobody is. And if that's the case, then it's not a problem with Microsoft, it's a problem with everybody, everywhere, that is within the reach of the US government. Which is everyone.
