It annoys me when people act like Y2K was apocalyptic scaremongering. No, Y2K was a real threat, which the human race spent huge resources to meet and thereby mitigated appropriately.
Those writing apocalyptic scare stories were poorly informed and deliberately trying to activate people’s base fears. AND there was a huge effort by very smart folks to avert it. No conflict.
But as a one-off thing it isn't really a big issue to a government, civilization or even an industry. At that level what does it matter if a few weeks are spent unnecessarily, once? Governments burn more resources than that on a slow news day.
Might not work on anti-vaxxers but it has shut down more than one stupid conversation about Y2K.
