I hesitate to install ad-blockers for non-technical users who would need support every time a website doesn't work. Many wouldn't be able to pin down the problem to the ad-blocker; they'd just think something was broken (seemingly randomly attributed to web browser, website, Internet connection, computer, something they clicked, etc.).
How do people here deal with that? I don't want support calls daily, and even if I did it wouldn't be a good experience for the users.
Interestingly, I think this is why Google is now cracking down hard on bad websites. They're trying to justify people not using adblockers. It's a losing game.
I suspect the remaining cases mostly come from email and social engineering, where most antivirus aren't likely to be meaningfully better than MSE/Defender/whatever the OS has built in.
