My experience is different in this scenario. I have got handsome deals from ads. Every body has its own experiences from ads
I get good deals from ads via emails from the re-sellers where I normally purchase equipment .
OTOH, a lot of their email, particularly that of Amazon.com, could just as easily be deleted as "spam".
"Things normally bought together", and, "recommended just for you" ads are the worst. First, for things like music CDs, 90% of those which they recommend, I've already owned for a couple of decades before Amazon deluded itself into thinking they were doing me a "favor" by offering them to me.. The remaining dreck, is almost exclusively things I wouldn't be caught dead listening to.
But more importantly, the follow up messages which in essence say, "you dun good by buying from us, so you should buy more", I find terminally offensive. Rephrased, "You didn't give us all your money last time, so how about if you cough it up now", just signals their greed in big red letters.
I don't know how much more plainly I could state the concept to you that, "the more ads there are present, the more ads the next seller must place to get their share of the pie. So, the amount of ads seems to be going up logarithmically.
If I want or need something, I'll shop for it. In other words, I'll go to the ads, in lieu of having them rammed down my throat.
Also, the concept that "ad blockers" are ruining business for so and so, is way beyond stupid. If people actually wanted to see and/or buy that crap, they simply wouldn't have installed the ad blocker in the first place.
So, Yahoo blows a bunch of sunshine up prospective ad buyer's behinds, and when it turns out they were lying in a bold face manner about the potential rewards of buying ad space from them, they blame it on ad blockers.
This is a concept traditionally referred to as "passing the buck".
"The dog at homework", same theme, subrogated blame.
Why don't you read up on "propaganda":

It might help level the playing field for you. Because you can be damned well certain whoever is writing those ads, knows it forwards and backwards.
