Yes, compliance and knowing how to wear a mask has been an issue. That's not the same thing as "masks don't work."
This is a random place to put this, but I just want to point out that I think for the most part even mask wearing is not required anymore (unless you are sick, but why are you going anywhere sick?)
Part of the reason I put it here is that I want to make sure it's understood that despite the fact I'm pretty pro-vax, pro-mask and generally supported the lockdowns at the time -- we're past all that for now with Omicron. Things are still a mess, and the facts on the ground could change, but I think it's important that everybody gets on the same page that we're moving on.
Regardless of a mandate, people will do what they do even if it's not in their best interests, or in the interests of their loved ones, or the interests of their neighbors. They will smoke in public places, they will goto work sick, they will drive drunk. Frankly put, people can be jerks. So you put a mandate out there, and you do your best.
Masks work. In areas where mask utilization is high, there is good air filtration and people follow distancing rules, the spread is slowed.
The surgeons already know. Since the 1990s, there has been a general movement away from using surgical masks in the OR, due to accumulating evidence that they have no effect. (For example, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480558/)
It is a literature review that didn’t find strong evidence for surgical mask effectiveness more because it hasn’t been researched deeply. And it notes that the absence of evidence does not indicate ineffectiveness of surgical masks, and rather a more significant research trial would have to be performed (and there were caveats to the feasibility of doing that as well).
Specific quotes from that article:
“What literature that is available on the subject tends to be dated with poorly explained methodology. There is also uncertainty over whether the results of such studies can be extrapolated to current surgical practice given the advent of new antiseptic techniques since they were completed.”
“It is clear that more studies are required before any absolute conclusions can be drawn regarding the effectiveness or, indeed, ineffectiveness of surgical masks. The published literature does suggest that it may be reasonable to further examine the need for masks in contemporary surgical practice given the interests of comfort, budget constraints and potential ease of communication, although any such study would undoubtedly have to be large and well controlled to prove causality given the low event frequency of surgical site infections.”
“It is important not to construe an absence of evidence for effectiveness with evidence for the absence of effectiveness. While there is a lack of evidence supporting the effectiveness of facemasks, there is similarly a lack of evidence supporting their ineffectiveness. With the information currently available, it would be imprudent to recommend the removal of facemasks from surgery. Instead, in the medical field where common practice can so easily become dogma, it is necessary to recognise the constant need to maintain a healthy scepticism towards established beliefs and to periodically re-evaluate and critically assess their scientific merit.”
Doesn’t exist.
I dont like being used as a lab rat. I refuse to participate in this uncontrolled experiment these public health experts are conducting.
At the end, they take the stance that while evidence doesn't support any benefit, it doesn't indicate harm either, so might as well continue using masks.
I don't deny that this is still a matter of controversy, compare Romney (https://pubmed.ncbi.nlm.nih.gov/11289767/) with Belkin (https://pubmed.ncbi.nlm.nih.gov/11886203/).
The most frequent complaint is that most research on the subject is not high quality, but what about those studies that are good? The most thorough clinical study is Tunevall (https://pubmed.ncbi.nlm.nih.gov/1853618/), which clearly supports no benefit. There are apparently no high quality studies that support benefit.
Some measures are simply common sense practices and don't need an overwhelming amount of scientific studies to justify them. Particularly when the drawbacks to them are so minor, while the potential advantages are huge.

Does it justify mandatory wearing of religious symbols and tattoos? After all, there are almost no drawbacks, and "potential" advantage is even bigger. It was considered "common sense" for millennia.
Before COVID-19, we had extensive analysis of previous pandemics, with the consistent judgment that public mask-wearing had no noticeable effect. For example, the DoD commissioned a study of the 1918-1920 pandemic. (https://news.ycombinator.com/item?id=30179067)
The latter question sounds insulting and dismissive, but it's actually posed in good faith. It highlights a genuine epistemological problem about the nature, limits, and validity of our knowledge about the pandemic. I can find studies on PubMed and elsewhere that back up virtually any belief, prejudice, policy, or therapy that I like. So can you. Where does that leave us, except with the obvious solution of trusting our local, state, and national health authorities?
I see virtually no evidence that suggests masks do anything meaningful to the spread of Covid—especially enough to justify forcing service workers to wear them 8 hours a day, 5 days a week for two years straight. Especially now that anybody can get a vaccine. Why should service workers be required to wear them? To protect fully vaccinated people who are still afraid of Covid? Seems pretty selfish to ask that if people. Especially when service workers get bullied and gaslight by rich tech workers who think “masks are virtually costles” while their only time masking is their 1 hour weekly trip to the grocery store…
These Covid measures are nothing more than forcing the lower class to protect the upper class (or at least pretends to. It’s all theater and we all know it). It is incredibly privileged to support any of the nonsense we’ve mandated the last two years.
Not my job, either. I'm not a doctor or public health authority. That's where I go for advice; do you have better sources in mind?
You might love masks but not everybody feels the same way. Leave people the hell alone.
"Leave people the hell alone" isn't an option, because you live in a populated, civilized nation rather than on a deserted private island. (I will note, however, that they won't shoot you at the border for trying to leave.)
From the 1918-1920 Spanish influenza pandemic onward, public health agencies have evaluated the effects of mask mandates and other non-pharmaceutical interventions. The consistent result of these epidemiological studies has been failure to detect a positive effect. A typical review article, which was I think the most quoted up until 2020 is Cowling (https://pubmed.ncbi.nlm.nih.gov/20092668/).
From the discussion:
In conclusion there remains a substantial gap in the scientific literature on the effectiveness of face masks to reduce transmission of influenza virus infection. While there is some experimental evidence that masks should be able to reduce infectiousness under controlled conditions, there is less evidence on whether this translates to effectiveness in natural settings. There is little evidence to support the effectiveness of face masks to reduce the risk of infection.
