When ads are hyper-targeted to niche products offered by small businesses that I am a fan of, they are actually not bad. I like the ads on Facebook, but not as much on other platforms like TV since TV ads are just random pray and spray ads, usually by megacorps for things I'd never buy.

Look at Dollar Shave Club. A tiny little company that was able to get to an insane valuation chipping away at the consumer mega corps because of targeted advertising and some good ads. I've heard that small consumer packaged goods vendors are having a tough time now that Facebook got their tracking shutdown. The only people who can effectively market mass market stuff like that now are the megacorps like Unilever and Proctor and Gamble who can do multi-million dollar poorly targeted campaigns.
