Indeed, their ever-changing "Get Windows 10" dialog is appalling. It's like a real life version of Cat Facts[1], or those stupid Best Buy emails I started getting after I bought a memory card from them and made absolutely sure I wasn't sharing my email address or signing up for anything. Hitting the "unsubscribe" link in the email resulted in more frequent spam from them, rather than actually unsubbing me.
Why should I have to spend any of my time on that shit instead of doing the work I have to do? I'm not a set of eyeballs for MS to sell. That shit might fly on Facebook or other free services, but the OS is a productivity enabler and that is all. The minute it actively tries to get in the way of my productivity in an effort to turn me into a product, I'm done with it.
