My flatmate is now a Linux user. But it took her so long to make the switch. What finally did it was when she sat down at a default windows 11 PC that I was fixing and we just opened the start menu saw a ton of ads and software applications that weren't installed and you had to pay for. I showed her that almost every single application has ads for products built in (co pilot buttons, one drive etc) and I said this is what you're going to pay money to upgrade to.

She installed mint and loves it. (I hate it because mint has so many small issues that are fixed in newer versions and it uses x11)
