(So I do think that performance advertising is partly a racket, but it can work really well if you know what you're doing). One additional thing people don't call out is that a lot of the budgets spent on these platforms are "learning" budgets. Agencies play this card really well. They'll tell you, "oh, you need to increase your budget, and test all these different combinations of ads/targeting/landing pages/etc so that you can learn what works (or the AI behind the platform can learn what works)". And obviously, in "learning" mode, you're ignoring the ROI. I've seen people spend substantial amounts of money in "learning mode", and the platforms are kind of incentivized to make the learning less efficient so it takes longer and more spend for you to get to ROI positive (or to learn that you will never get there).
