Should you block ads? Are you stealing revenue?
How about, why do we think that ads serve any purpose what so ever? In every company I've worked, the sorriest and dumbest people worked in marketing. How is this allowed to continue? Business managers STILL have no idea what the internet it. Ads worked on TV. People were trained to always watch their shows on a particular day at a particular time. The advertisers bombard the viewer with the same ad over and over until it is part of their psyche. That can sell widgets. But the same is NOT true of the internet. One person seeing one ad at a random time does NOT sell anything. This is one of the reasons that the advertisers want your demographic. They over have a couple of shots, and they want to make sure you see the most appropriate ads. But a random pop up add DOES NOTHING. It sells NOTHING? So why?
If a product sells, it is 100% due to the marketing campaign.
If a product does not sell, the marketing department needs more money.
At least that's how the executives think it works. And it may have worked like that 50 years ago. But not now. So FUCK THE ADS. All ads. By being "nice" and viewing a page's ads DOES NOTHING. It is pointless. It is a waste of time. It's moronic. It sells nothing. If you want something, you can search for sellers and information on the products. Then make your decision. I suppose that there are people so superficial and gullible that they will buy a product due to an ad. But they are few.
It is ONLY the myths of marketing that keep the ads around.
