Please forgive my personal pet peeve, but nothing BurningFrog said was a straw man as far as i can tell. I don't see any way they misrepresented your argument.
“Giving away their vaccine” is the straw man. There is a huge range between free and maximum profits. I’m not arguing that they shouldn’t be incentivized with a profit, the question is how much and what's in the best interest of the American people, not just Pfizer and Moderna.
