What a totally disingenuous comment your own links acknowledge the nuances about differences in effectiveness between the types of masks and how you wear them.
To breakdown each of your sources.
1. It specifically notes the cloths masks are less effective and the cloth masks they tested were double layered and made from a water resistant material. It also discusses the need to wash them daily and not to take them off in a given sitting.
Where ever I am I seeing people violating these guidelines. Whether its grocery store workers pulling them down to catch a breath or people at restaurants taking them off and on to eat. Also I see tons of people wearing single layered non-water resistant fabrics. And how often are we all washing them? Probably not a lot.
2 & 4: Both focus on looking at observational data comparing places where masks wearing is prevalent versus places where it is not. It even looks at the same places after switching policies. But these are obviously confounded by a whole bunch of other factors. Maybe places that wear masks are better about physical distancing and washing their hands. I find it difficult to take much from this kind of evidence, but I understand why someone else would.
3. Similar to (1), but even harsher on cloth masks. Specifically notes the effectiveness of respirators, says medical masks were not effective and cloths masks were less effective (I don't know how you can be less effective than not effective). Here is the actual line.
"Randomised controlled trials in health care workers showed that respirators, if worn continually during a shift, were effective but not if worn intermittently. Medical masks were not effective, and cloth masks even less effective. When used by sick patients randomized controlled trials suggested protection of well contacts."
This is in no way equivalent to the arguments for climate change. And frankly thank god you aren't a public health expert because by comparing the two publicly you would be doing damage to the environmental movement.
Instead of just trying to make someone look dumb on internet why don't you actually engage in a good-faith argument that acknowledges the very real nuances.
