thing is that you gotta compete for brainspace with everyone else who's running ads - sure, you'll piss some people off, but you've also put your worms in their brain. Even if it's a net negative sales wise, because your competitors are also bidding for ads, the price will just stabilise at a lower point if you don't go for it, and then the enemy brain worms will have infiltrated the consoomers mind instead. Basically, if you're a big company you've gotta do marketing. Bonus feature is that it's constantly telling people that if they buy something they'll be happy, which is pretty effective capitalist propaganda (marketing guys don't think about this but it's their main function lol)
