What a strong negative opinion, really proven my point. Ads by definition are very broad, maybe you only see ads only in the form of tv / youtube / mobile game ads that halts your activity and forcing you to consume the ads content.

Ads also comes in a form of storefront banner. By your definition, then there shouldn't be McDonald's logo on top of their shop's front door. So how can you know that building is a McDonald's?

Yes, it is generally intrusive and non consensual. But if you say nobody ask for ads, you're very wrong. If you're going to a forum to get game recommendations, you're looking to be advertised. Steam recommend section or hot deals or storefront page are all advertisement. Game trailers are advertisement. They just don't really feel as intrusive as yt ads, and an example of good ads in my book.
