I see what you are saying, but you are not correct on any of these points. 'depends on cost': It can't actually depend, on average. Advertisers keep spending money because they make more back overall than they spend on advertising. Only a small fraction of that increase in income is paid in fees to the platform that is funded by the advertising. To make the same amount of money, the platform would only have to charge you a small fraction of what advertisers are making off of those same users. Advertising isn't a battle of wills, it is leveraging psychology to manipulate you in ways you aren't even aware of. It works on you just as well as it works on everyone else, if you don't think so it probably works better than average.
