I can definitely see your definition, too. But it departs a little from the ad blocker conversation. I don’t need an ad blocker so I’m not fooled by a pyramid scam. I do need one to keep malicious code away. The kind of person who falls for this sort of scam doesn’t know how to install an ad blocker, probably.
But then again, there’s the “I install the ad blocker on my mom’s computer to keep her from falling for scams” argument, which is definitely valid. Yeesh the last time I visited my elderly father he had all kinds of XXX push notifications popping up from calendar spam he’d fallen prey to. He was in a state of desperation, always afraid someone was going to see his phone do something embarrassing.
