Advertising unethical

I’d say it’s not inherently unethical. How else would you find out about options for a thing you need?

How current the ad industry works however, can die in a fire.

You can just search for it, you don’t need ads for that. Ads is a really bad way to find out about options, because it’s never about quality, it’s all about appearance.
How would you know what to search for? Some advertising is fine - a sign for a restaurant or industry mailers or magazines, “related products”, etc etc are all very tame forms of advertising. The problem is hyperintrusive advertising which has now spiraled so far into hell that it drives a model of data harvesting and content slop that’s slowly tainting all access to information we have.

How would you know what to search for?

Because of the needs I have, when I am hungry ill search for recipes or restaurants. When my apartment needs cleaning ill search for cleaning supplies, when I am bored ill look up what movies are playing.

I actually can not come up with a single situation where advertisement would be needed or helpful in anyway. I also do not have a problem with smaller advertisement, but in my dreams they are all banned regardless. Won’t be missing those.

Okay, to break down the point: search for them where?
I see what you’re saying, but the obvious distinction here is that if someone is actively searching e.g. Google for a product, they don’t mind being shown products (and by extension being advertised to) - they’re actively seeking it out. What everyone has a problem with is being shown advertisements for products when they aren’t seeking them out and in fact actively want to avoid them.
Thank you! The unending intrusiveness of modern advertising really has killed and buried the useful parts of advertising by becoming the norm, I wholeheartedly agree.
