It is a product, just not for consumers. Other companies buy the product and it is applied onto the consumer, to the consumers distaste.

Advertising is itself always balancing on the tradeoff between disgruntling the consumer and the benefit the consumer gets from the media/tool they're actually trying to engage with. It's an implicit bargain for most people, not an explicit one.

For me, advertising crossed that line a long time ago. If I had to watch the amount of ads YouTube actually puts in front of you, I wouldn't use it. Thank goodness for ad blockers.
