For 10, unplug ethernet or do not connect to wi-fi and it should all you to continue or allow you to skip creating an MS account.
On the one system I use for gaming, before I install 10 which I have done a few times, I shutdown computer, physically unplug ethernet cable, then turn on computer and start the installation process, and I've created a local account everytime. Do not plug in cable or connect online until Windows has rebooted to the start desktop with Start menu. If you connect during installation it could force you to create online account.
How are people surprised? How is this news?
The second you mentioned Google you're talking about an all-seeing totalitarian state. Nothing you said about imbedding tracking links in docs is surprised. As a corporation they are always developing new ways to pimp you out and make you turn tricks for Google without you knowing while they keep all of the pay from your actiities.
Google tries to turn every human on the planent into their personal money making whore.
