I have. I've skimmed through the PDF, and it seems he wants to highlight the "ineffectiveness" of cloth masks, and downplay benefit from other types. It is also odd to put "cloth masks" in the title, if that is not the main focus of the review.

I can't speak to the framing of the paper or the title. Maybe that's where he felt the evidence was least solid (which I understand; there is almost no evidence supporting cloth masks).

Regardless, the paper covers pretty much ~all of the prior literature for masks and respiratory illness.
