Wow...These are garbage.
globalresearch.ca - the overview is written by "Swiss Propaganda Research"...I'm just saying...suspicious name. The site itself doesn't look extremely credible ("Turkey’s “Secret Plan” (2014) to Invade Greece and Armenia?"), but we'll ignore that.
This one lists a lot of other sources and seems to misrepresent the findings:
http://www.asahi.com/ajw/articles/13523664, the doctor who did the study acknowledges that masks can prevent droplets and stop people from touching their mouths . The conclusion of the article says people should check that their masks fit tightly and that there are no gaps to leak...so, they didn't say don't wear masks.
Several of the source articles say that we don't know how effective masks are, not that they don't work.
https://www.aier.org/article/the-year-of-disguises/ - no studies, just a guy sharing his opinion.
https://pjmedia.com/ - this article has a correction at the beginning since the original publication.
https://www.globalresearch.ca/covid-19-masks-crime-against-humanity-child-abuse/5726059 - Again, no study, or research, just opinion. Oxygen deprivation? Really? So which is it? Are the masks not stopping tiny viruses and they are useless or are they depriving people of oxygen?
https://www.thegatewaypundit.com - the magazine that published the study has retracted it for being misleading - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8114149/
The Editorial Committee concluded that the author’s hypothesis is misleading on the following basis:
1. A broader review of existing scientific evidence clearly shows that approved masks with correct certification, and worn in compliance with guidelines, are an effective prevention of COVID-19 transmission.
2. The manuscript misquotes and selectively cites published papers. References #16, 17, 25 and 26 are all misquoted.
3. Table 1. Physiological and Psychological Effects of Wearing Facemask and Their Potential Health Consequences, generated by the author. All data in the table is unverified, and there are several speculative statements.
4. The author submitted that he is currently affiliated to Stanford University, and VA Palo Alto Health Care System. However, both institutions have confirmed that Dr Vainshelboim ended his connection with them in 2016.
