Read the EULA and don't confuse what they have implemented so far versus what the EULA allows them to do.
If you want to be tracked and your usage data sold, that's fine with me. But I choose not to see ads personalized or not. I can block google from tracking me (https://www.eff.org/privacybadger) , but you can't stop MS.

When MS sends me a check each month for using my PC, I will consider, but as I am the one paying for my internet service, I'm not letting anyone use my PS to help you get your downloads faster. As if MS had us in mind rather than their server and broadband cost when they implemented this.
MS is in the business of foisting upgrades on their consumers which benefit them instead of their customers. Win95 promised a quantum leap in computer speed and yet it was 40% slower than the OS it replaced (W4WGs). American Businesses averaged in-house cost of $2500-4500 for the upgrades in hardware, training, downtime, IT costs all so they could go slower.
Glad you haven't been affected by these updates and that's fine if you just use your PC for entertainment. Well that is unless you were an SLI user and had WU break SLI, ... yeah, you could fix it by installing the correct driver from nVidia, but then WU would recognize that you weren't "compliant" and just reinstall the broken MS version all over again... and again.
"Update and Shut Down" is no big deal except when you are paying your employees to sit there and do nothing. I have a business to run. I can't afford to have staff sitting around for 3 days when Windows Update shuts everyone down. With SP2 for WinXP thousands of CAD operators were left sitting at their workstations twiddling their thumbs because the update broke the AutoCAD licensing scheme and it took 3 days to get a fix
Or how about these "known issues"

Where is the harm in letting a user sit on those updates, read about any problems users might have had with particular hardware combinations before installing and holding off until those problems are resolved ?
If I need support MS charges $499 for an "instance", ho much can I charge MS when an update has my employees sitting idle ? In 2008 and 2012, we had to take responsibility for any fines imposed by the IRS for getting tax forms in after April 15, as we "elected" to install those updates, but when we have no choice, or unsavvy users don't know how to stop them, why shouldn't MS be responsible ?
