I fully agree with everything you've said, but crucially, I don't think this article, or the others like it, are actually recognising their own vulnerability.
The framing isn't 'I fell for this and I was wrong', but 'I am the first one f all of you to see the truth'; there's no humility, no recognition, just the exact same self-delusion, which means they'll fall into the next pit head-first as well.
Fair enough. I just have a soft spot for people recognizing that they've been duped. It happened to me personally and I know it's a pretty difficult thing to go through. So I just tend to give a lot of grace even though the person might be an asshole as they deconstruct.
