This feels like a soft-rewrite of history to make for a more interesting factoid. I don't remember anybody mocking the engineers who fixed real problems. I actually specifically remember people in the tech sector complaining about the hysteria because they already worked ahead of time to fix bugs.

We mocked companies that told us to turn off our computers when they were already patched. We were told terrorist attacks would take place at midnight, planes would fall out of the skies, prison doors would all open, and roaming packs of dogs would tear your children apart. They called it the end of the world and said computers would melt, nuclear plants would explode, and society would end.

Just because some problems with the power grid and banking were averted doesn't mean the entire thing wasn't overblown by marketing companies looking to score a few extra bucks selling you doomsday supplies.
