I am an anticapitalist, and I am acutely aware of what I am against. Advertisements, and how they solidified in the 1800s to current is one such thing I'm directly against.
I've also seen Rome Collesuem's chiseled graffiti to what amounts to "eat at restaurant". Rudimentary, when compared to hiring psychologists to extract as much wealth by exploiting the human psyche, but they were adverts nonetheless. And even those shat upon infrastructure and the humans who were there.
I do think there's a gradient of unethicalness in advertising. If I'm looking for a thing, and shown lists of things that match what I'm looking for, it's at least consensual behavior.
But these days, advertisements are anything but. They're invasive, insidious, and many a time try to fool the human that they're legitimate (and not paid) content.
But I'm guessing the emotional words you chose to use tells me you're probably in adtech.
