It doesn't need to be a global/political conspiracy for people to be more sensitive to a large amount of people dying after almost 20 years of significantly lower death rates.

Edit: Also, looking at overall deaths per million is not anything like comparing actual mortality rates of those infected. The baseline mortality in 1918 was already way higher and the pandemic amplified that, despite actually being less deadly than COVID-19 at an individual level. So I'd argue that the response to this pandemic was more than merited and was appropriate to the nature of the virus itself. It was not just another "asian flu."
