They’re using their computer, and when it’s time for an upgrade, they buy whatever suits their needs.

This always weirded me out - people who don't have any investment into Windows in the form of understanding are the most reluctant to even think about switching. I understand "advanced users" with their trusty FAR or TC and in general workflow which didn't change much in 20 years. But people who only use a browser?...

I think it's actually a rhetorical problem on my side. There's been a few cases where people (normies at that) who'd be utterly intolerant to the idea of leaving Windows switched to Linux on their own without my help in the periods where I wasn't meeting them often. It's as if my attempts to proselytize were counterproductive.
