Nike, P&G and Apple will get by if they can no longer advertise because they're firmly entrenched in people's minds. But if you're starting a competitor, or any new business really, I don't know how you'd find customers without ads. If someone's saying "just use product hunt" or some other website dedicated to new products, they should remember that the vast majority of new businesses are small, local ones - barbershops, florists, massage parlours etc, not tech startups that will eat the world. It doesn't necessarily need to be targeted web ads, I suppose you could use newspaper ads, or TV or physical letters, or spam email. Any of these work, but I think a new business would probably get the most bang for buck by targeting.
