Ads should just be banned anywhere in general.
They concentrate power to those who already have it, because you can make more ads if you have more money. The local burger joint cannot compete against macdonals on advertising, the local soda against coca cola.
It's ugly, eat attention, and interrupt.
It creates business models with terrible incentives, which leads to censorship in medias, quantity over quality, attention driven content, etc.
It encourages mass surveillance, and is used to influence society in the worse ways, making it dangerous to democracy.
Finally, if you remove ads, suddenly you get a much better filter for things: if people don't think it's worth even a little bit of money, let it die. It was not worth it.
Besides, even if you pay, you still see ads. You see submarine articles in paid newspaper, ads before your movies in the theater, ads in your bus ride...
Can you imagine, all this ads money, now free to be invested in something else?
