Outside of gaslighting's original context in a relationship, I often see it used to refer to a form of strawman argument. I read the gaslighting comment as saying that the person knows that virtualization in the form before Kubernetes was not sufficient, but tries to make people who express that thought feel like they're wrong at a fundamental level. So the implication is that the author knowingly constructs a strawman argument and then tries to make it sound like anyone who recognizes it for what it is, is "crazy".
