You say everyone hates then but honestly it’s really not true. Plenty of people are annoyed by ads, others tolerate them, sometimes people even enjoy them (see Superbowl shit or people sharing meme ads and commercials) and honestly that’s part of the problem. Ads have been a part of so many people lives for so long they can’t even imagine a world where they aren’t constantly bombarded by ads and having them privacy exploited for corporate gains.
Personally I’m vehemently opposed to ads and go out of my way to block them in every way I can, but fundamentally many people don’t see them as an issue or are too attached to the corporate teat to try voting with their wallet to suppress the problem.
