I'll bring out the "computer has viruses" argument. As in:
"Remember how you asked me to clean your computer from these toolbars and make it faster? This problem may happen again if you browse the web without uBlock Origin installed. Chrome doesn't support it now, so you have to use Firefox. Ignore websites pleading you to switch back to Chrome. Some of them will try to sneak in this toolbar garbage to you. Actually, stop visiting such websites because they're staffed with assholes who want to abuse you. But if you must, do it in Firefox. Yes, preferably in Private Browsing."
As others said, regular people follow the tech crowd. My family uses Chrome because that's what I've been telling them to install and/or installing for them for the past few years. But the very first thing I also install for them is uBO, and if that stops working, Chrome goes out of the window.
