My mother and my partner's mother respond every time to those full page takeover ads that mimic a windows dialog box and play scary audio about viruses, tell her to call / give someone her credit card / let them remote into her computer. It's utterly infuriating these parasites are allowed to buy ads.

I aggressively install ad blocks and add domains to /etc/hosts to prevent having to remotely reinstall OSes every couple months.

These are the people google is trying to help with this move, imo. Because ublock still breaks pieces of the web, but they can't be trusted to browse the web without it.
