Well, I mean, he's right: any time a story seems outrageous and unbelievable, it's often because it has been embellished at least somewhat. That doesn't mean it's completely false either, though.
"Often"? Would you be so kind as to show me your data on that? Maybe it's just this election season, but I seem to be hearing about quite a lot of outrageous things that are perfectly true.
Even if you're correct and he's merely saying something generically true about almost any concerning story, him saying it in the context of the post reads to me as a veiled accusation.
For example, suppose you posted an open-source project of yours here. If I were to comment, "Open-source projects are often half-finished, buggy messes," how would that seem? It is factually true; randomly looking at GitHub projects is enough to show that. But in context, it's an unkind thing to say because encourages people to look at your project as one of them.
