Are you serious? You literally answered your own question with the very next sentence.
What? The original argument was “Just because it exists doesn’t make it good.”, implying that it (click-bait thumbnails) doesn’t necessarily work. To which I said that the fact that it exists means it works. To which you seemed to object by saying that there may be people who have an interest in it existing - like they want it to exist despite it actually not working. I’m confused about what it is you’re saying.
You can go and read my comment again if you’re confused. It’s pretty clear that I was saying your original argument might apply to YouTube titles, but doesn’t apply in many other parts of life.
Since Youtube is what we were talking about, I see no reason to assume that wasn’t what you were talking about. Also, I do think that the principle can be applied in most situations, some more easily, some less.
