The title is the opposite of click bait, it repels potential readers with its apparent obviousness. The article itself is actually interesting, it's an argument against learning from bad examples. Perhaps a better title might have been:
Bad Opsec Considered Harmful for Learning Good OpsecI was like "wow, I haven't seen a considered harmful article in a while, the quiet must be ancient", the I saw the author and it made sense.
When he says something, it's usually worth a listen.
Good to see he talks about the three Cs. It is the easiest way to quickly grok OPSEC in my opinion.
