You are mixing different entities. In advertisement business there are publishers, providers and users.

Publisher wants to advertise certain product or service. Provider gives him means to do it (serving advertisement media such as ads, banners, etc.), and users sees and uses (or ignores) these ads.

Now, there is an agreement between *publisher* and *provider*. Let’s say publisher pays to provider N amount of money so it will show his ads M amount of times. And if user acts on those ads (for example clocks on them), provider gets extra money.

Note, there is nothing about the user here, the agreement is solely between publisher and provider. Now, let’s say I don’t like ads. I consider them all spam and waste of my precious time. I don’t like looking at huge signs along the road, which distract and cause accidents, I don’t like paper spam in my mail, digital spam in my e-mal, and flashing and blinking ads all over the web. What do I do?

I block them. Have a right to. Something is just to hard to block, and the way is just to look away (for example huge sign near the road), but other stuff is easier to block. That’s why he have spam filters and etc.

Now, having adblock in a browser is just like not looking at an ad (wearing filter glasses if you like). I.e. the provider doesn’t break the agreement with the publisher. It tries to serve his ads. But I don’t like them – I don’t look at them using tricky technical means. Alas, the provider is not getting paied possible, depending on his agreement because I don’t want to look at his ads. The publisher doens’t get his income from my interest in his stuff. But it’s their issue, not mine.

It’s a personal and rightful choice, whether to look at ads, or to ignore (block) them.
