That's the problem with framing everything that way. This HN comment is marketing for my brand, my username, I sell t-shirts on my website! That's not why I'm commenting here, but the term is that broad because we're using it colloquially. It's a human psychology thing that I get entrapped into too. Calling it out doesn't make it not work. When you use the lens of marketing, your comment is marketing that you are not marketing, which is a specific category and advertising profile to be filed away in a database somewhere, if we go to the theoretical extremes.
