I feel that the vast majority of folks would claim they'll 'never buy anything from ads'. Isn't one of the main benefits of advertising purely brand recognition?
I'm unsure how I feel about the 'zero chance to ever serve vast majority' argument. I use uBlock and Sponsor Block, but recognize that that has an impact at scale. I guess that argument kind of feels to me like "your single vote doesn't matter." For a few hundred or thousand folks, sure. But what if 500k people start using it?
