Also, let's be honest: a lot of replies from people who need to believe this is ethical because they want to reserve the right to use (or already use) this dark pattern in a product as a "growth hack". Or people who work for an employer who already uses dark patterns of this nature. Startups are rife with this kind of abuse.
Yeah, I've noticed that on HN with some scammy business practices, there is a definite case of "It is difficult to get a man to understand something, when his salary depends on his not understanding it." People would rather this is allowed and it becomes a game of buyer beware, because in many cases they are the sellers and know the average buyer will not beware.
