[I]n this context I trust Microsoft about as far as I could throw a heavy old steel-cased 1980s PC.
Being careful with your data isn't just a Microsoft thing. My views of Microsoft and Google are pretty much diametrically opposed -- I have enormous faith in Google and Googlers doing the right thing with respect to protecting the data I share with them, but even in the case of Google -- with whom I share a great deal of data -- I'm selective about what I do share.
Anti-Microsoft, pro-Google, and no stated reason for faith in one "doing the right thing with respect to protecting the data" while the other, apparently, will not.
Except for this:
You may have heard concerns about the sharing of Wi-Fi passwords by Win10. This is largely not a problem in practice, given the details of the implementation.
How this suffices for posting on Slashdot with the headline tease "Privacy Mess" eludes me. Google = Bing. Google Drive = OneDrive. Chrome = Win 8+ windows-account-synced favorites and settings. Pot and Kettle both the same color, black or otherwise.
