Why should it be any different for ads? Advertising is a cancer on society, by itself its purpose is to waste some person's time by showing them something they haven't asked for, sometimes in hope to drive a purchase. We've basically normalized intentionally wasting people's time (in aggregate this time can be expressed in human lifetimes) for the benefit of a select few (the advertisers). Advertising also has secondary negative effects where it perverts the incentives between service providers and their users (social networks' objective is to make you look at ads, not facilitate communication with your friends/family), sometimes up to the point where said service providers promote harmful content to drive ad views ("engagement" as they call it) where said content then leads to mental health issues, broken relationships and crime (like the radicalization of the right-leaning Trump supporters that ended up storming the Capitol).
