Unlike China, Germany is under the thumb of the U.S. Their state prosecutor won't even start an investigation into the tapping of Merkel's phone because 'there isn't sufficient evidence'. Never mind that the U.S. gov't admitted to it.
I don't think Germany or any other E.U. countries will follow.
The first thing Microsoft does when they learn about a zero-day is to hand it to the NSA. Microsoft doesn't get to fix it until the NSA tells Microsoft they're done exploiting it.
Google may be pissed about this. They've been pissed off before about NSA's shenanigans.
