That’s why the ad-funded internet is referred to as a bubble and people are saying that the bubble will burst. It’s money-making based on the promise it’ll make the company paying the advertiser money, without any guarantee. You can’t make money out of nothing, people have tried and failed for years if not decades, it always comes crashing down, either through crypto scams, pyramid/ponzi scemes or though worthless investments like the Dot-com crash, it’ll always blow up in your face sooner or later. Which is what is slowly happening with the ad-funded internet, it is becoming overvalued similar to the dot-com investments.
