The behavior of click-bait ads isn't terrible in a way that should cause someone to question their own ethics. You may disagree. So what? You aren't going to fix the human condition by drawing a line in the sand, nor would it be moral to do so. The price of skepticism is uncertainty and the price of certainty is extortion (in terms of clicks and attention).
I would not include such bad behavior from some bad actors as part of the "human condition" but outliers on the fringe because I believe most people want to be good and do good things, but apparently not these assholes.
It is. You take the good with the bad. There's not a lot of evidence this is "bad" within that spectrum. It's very subjective, since I never had to question my ethics when working in advertising. There are things I will do and things I won't, but I don't champion the eradication of those things I won't do.
