I believe the issue we are discussing is customer support. MS used manipulative techniques to supply this supposedly amazing offer. No way to refuse the so-called "offer", which of course leads to repeated nagging to add a ton of impedance to those who would have otherwise resisted upgrading, finally culminating in unexpectedly bricking the computers of some users who were perfectly happy with what they already had paid for.

I had a old Windows 7 laptop which I updated to Windows 10, and promptly the touchpad right click stopped working. I didn't really need that laptop at that point, so I just threw it away and also decided that I am never going to use Windows OS after that point unless forced to for work purposes.

To me, this "offer" takes top spot as the current gold standard for shitty support.
