Uh... I mean, you don't really think that person has an accurate understanding of what actually happened? Because I'm having a hard time trying to imagine that. It's not that there aren't any vulnerabilities in curl that can be exploited that way, but I struggle to think of situation where curl would have been an actual culrprit. Also, it sounds like he thinks curl is something purposefully malicious.

On the matter of "inevitability of progress": yep, I even think it applies to much bigger extent. I just don't see how is this connected to the troubles of the-victim-of-curl guy.
