Not sure what the fuss is about, the same old rule applies: if you want your data to be private, don't use any form of cloud services - server based voice/video chat, cloud storage services (google drive, skydrive, icloud), digital assistants (siri, cortana, google now), any contextual based delivered services which "learns" anything about you to provide you with any form of automated and/or dynamic experience.
If you want to be treated like you live in a box, then you're going to have to live by it.
Everyone complaining and "fed up", closing their MSDN accounts, boycotting MSFT products - you're in an echo chamber which won't be felt as our devices become more service oriented rather than boxed solutions. MSFT is trying to stay relevant, not undermine their massive user base. Whether it is right or wrong, I don't have an opinion on, but if you think MSFT is a pioneer in this space, you're being unjustly biased.
