Let's assume you are correct.
Your claim seems to presuppose that the author believes the opposite of what the piece suggests ("not a good faith argument"). Why did the author go to such lengths to design this propaganda? Why do they want to make people doubt the public health establishment? How do they profit from that?
I could see claiming that they are wrong (though I'm not qualified to evaluate that), I just don't at all understand the claim of bad faith.
This is usually how I feel about claims of bad faith in general (and the internet is lousy with them of late). Maybe I am just naive. I tend to think it's more likely that people believe what they say and are potentially incorrect than that they are incorrect and know it, yet still make the claims anyway.
