"Ads are inevitable."

Not at all. They could even be prohibited by law, as evidenced by prohibitions of some ads being common in most jurisdictions and the Clean City Law of São Paulo.

One of the grand old men of modern advertising said that "man is at his vilest when he erects a billboard", and suggested that he would eventually turn to covert militant direct action against it. I suspect that he would have extended this to screen ads if he had lived long enough to experience them.
