People have disliked ads since ads existed. Carl Sagan's 1985 book Contact includes a brazillionaire S.R. Hadden who made his fortune by inventing an adblocker for television. https://en.wikipedia.org/wiki/Contact_(novel)

For those who haven't learned their lesson yet, I doubt anything could move the needle.

The FBI has previously recommended running adblockers as a method to prevent malware and especially scamming. Nobody cares much.

It’s a low-hanging fruit that has high value, particularly for less savvy internet users. Scams have always been the biggest threat. I’d say the majority of internet ads are scams, and the platforms often don’t make it clear what is or is not an ad.

But, we always knew the risk of malware was there. In the modern age, ads are basically never delivered as static assets. They’re delivered as small applications, with code. So, we’re relying on our sandboxing mechanics to work perfectly, and predictably they don’t. The solution is to block the code altogether; to block ads.
