The link you provided certainly communicated that masks had little benefit and had a section on the "dangers" of wearing masks.
I paraphrased, but here is a direct quote;
"Conclusion Face masks in the general population might be effective, at least in some circumstances, but there is currently little to no evidence supporting this proposition."
Your link provided a 7 point section entitled G) "Risks associated with face masks"
and provided the means to share the research on twitter and facebook at the top and bottom of the page.
Am I wrong that the page contained charts that seemed to suggest wearing masks seemed to cause the increase of covid infection rates? Correlation does not imply causation, or so I have read.
So, in answer- No I found the page findings questionable and so I googled the source- which also suggested that may not be a high value source of info and that it seemed to have a distinct bias.
