I honestly don't understand which bit of this quote, from your own source you don't understand:
“Seriously people- STOP BUYING MASKS!” he wrote. “They are NOT effective in preventing general public from catching #Coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!”
Is he saying that N95 masks don't work at all? That they only magically work for healthcare professionals?
Or is he very, very, clearly, even within the limited confines of a tweet, explaining that N95 masks are better allocated to frontline medical staff than being randomly worn by low risk people in low risk locations doing low risk tasks? That using those resources more effectively will save more lives and that people in those lowee risk situations can easily get protection by keeping a safe distance and following other sensible precautions that they list.
I can see how someone could intentionally misrepresent what he says, but I don't see an honest way to make that mistake.
