Yes, "doesn't everyone use adblocker?". Possibly. Maybe that's why I didn't get more money. I certainly use an adblocker. But there's clearly some subset of people who will see the ads. Some company policy bans adblockers. Or someone's using a public computer to do some browsing.

Or they're browsing on a phone. There are fewer adblock solutions for phones, to the point where adoption is basically nonexistant (I don't have data to back this up).

So seeing as how I dislike ads, why would I subject anybody else to them, if the money it gives me is insignificant to me?

It's the golden rule. Don't do unto others what you wouldn't want done to you.
