Re: I'll jump in before everybody starts to state the obvious....
Firstly; Fuck you Microsoft.
Now that that's out of the way; is there any one person surprised by this stunt? As disgusting of an act as it is, given Microsoft's recent history it was only a matter of time before they implemented adware (maybe even viral?) payloads bundled alongside "security" updates.
Experienced users (incidentally enough many of whom possess purchasing powers over corporate software licenses) were becoming more and more aware of which KB numbers to avoid on Windows Update (namely 2952664 & 3035583) and thus Microsoft needed a new strategy.
You know what though? Whatever. Yep. Whatever. I don't even get angry anymore. I just read the news, and laugh. Why? Because I know that Windows is on its final days on my PC. Microsoft has already projected to me their true colours quite a number of updates ago.
And to all the Microsoft apologists and supporters of Windows 10: look, I respect some of the technical achievements of Windows 10. I respect that it runs much better on low-end hardware than Windows 7 could ever hope to achieve. Windows 10 is certainly not without merit.
What I do NOT respect nor tolerate however is Windows 10's lack of respect for MY privacy and MY preferences. I, for one, like to only update drivers when absolutely necessary. Not every single time a silly optimization update is released for a game I do not play or feature I do not require (which then crashes my PC when I launch a web browser). Likewise, when I say that I prefer so-and-so application to open my text or even PDF files, I expect the operating system to honour my preference and to not decide that it knows better every second Tuesday of the month.
Thus, until the day there is a big AND universal "telemetry off" button (which is guaranteed to be honoured 100% of the time and never to be reset in the future for whatever reason) and until the day I can control what drivers I want on my PC, Windows 10 can install itself where the sun doesn't shine.
Oh, and did I mention? Fuck you Microsoft.
