I disagree. Advertising is a zero-sum game. If nobody advertised, every solution would be equally discoverable via search and word-of-mouth.
It's only when some actors start advertising that the others must as well, so they don't fall behind. And so billions of dollars are spent that could have gone to making better products.

It's basically the prisoner's dilemma at scale.
