People don't like it when their worldview is challenged, but I think it's still important to discuss these sorts of things. I sometimes refrain when it's clear the other party won't consider my words at all, but still...😅
On the thread's topic, modern marketing / advertising is the calculated process of removing free will from a subset of the population via scientifically tested techniques, thus, I do not believe it to be a moral action; magickally speaking, the closest thing would be mass mind control. Nonetheless, as a business owner, if your competition is using these tactics, your chances of survival drop considerably if you don't use them as well. When you have other people, such as your family and employees, on the line as well, the line between right and wrong is then blurred.
Again, business is no different from warfare. If you wage war with weapons, your victims die quickly (ideally, most of the time), but if you conduct business, your victims die a slow and agonizing death. Both situations are still the responsibility of those up top.
