It does matter whether the science is misprepresented, causing irrational anxiety in people, which also increases your risk of "so many diseases and death".
Respiratory infections generally increase your risk for various pathologies, but so does staying indoors in fear, not getting exercise and avoiding social contact.
Considering the impact on peoples emotions and behavior when communicating data (instead of just warning them of these possible pitfalls) is an extremely slippery slope that quickly leads to an impairment of the sensemaking process. Be it due to self censorship as well or a loss of trust when people recognize they are getting managed. In the end its not anyone call to determine what information and expected reactions would be better for other adults.
I find it a lot more fruitful to elaborate why the data doesnt support those conclusions. This way we dont risk slipping down this slope and instead actually help each other fix our errors.
