While I understand the sentiment, most ads for a long time were fairly reputable? Like in the news papers, most ads were to make you aware of a brand (next car I buy I'll feel safe buying X because I've seen it in the papers), or to notify you about a local store having a sale etc. And disabling my ad blocker and going to a page I see ads for house listings nearby, offers to buy sports gear in a store in my city, and ads for a well known telecom company. All things I would trust.

What I don't understand is why high-value brands sell their screen estate to straight up scams or low quality ads.
