Blaming the victim is doing nobody a favour either.
The distinction between “windows is upgrading on its own and there was nothing I could to to stop it [once it started]” and “microsoft used a bunch of shifty tricks to fool me into pressing a button that supposedly gave my consent, and then there was nothing I could do to stop it” becomes pretty moot, pretty fast.
Yes, the latter is technically correct, and should be the main focus. But for the victims who are wondering what the fuck just happened, a snide, “did you read the dialogue before closing it?” isn’t helpful. It comes off as smug because because you consider yourself superior.
If there was more nuance to your original comment, you probably should have made it in the first place. Your one-liner only came across as snark.
