I agree that is true for the UK (as far as government policy goes). The UK has an actual sensible policy that knows that masks are mostly bullshit and that distancing is what matters.
I've previously posted a summary of the anti-mask literature
here. You clearly have never read it or you would be more informed. The mask literature is all over the place and low quality evidence and science. If you used your common sense, you'd realize that's why for many months the CDC and WHO advocated against population mask wearing. The entire sum of the literature held no good evidence they help at the population level.
Let me quote you some keys bits:
Ventilation kicks the crap out of masks. Yet only some governments are pushing for more ventiliation, having a false sense of security in masks:

Ventilation. Even the opening of an entrance door and a small window can dilute the number of small droplets to one half after 30 seconds. (This study looked at droplets from uninfected persons). This is clinically relevant because poorly ventilated and populated spaces, like public transport and nursing homes, have high SARS-CoV-2 disease transmission despite physical distancing.

Randomized clinical trial of standard medical/surgical masks in health care workers (2010, Australia).

Study was spurred by the H1N1 flu. While N95 masks offered protection against respiratory illness, medical mask wearers and control group numbers were similar.

17 eligible studies. One study had improvement with mask plus hand sanitizer. None of the studies established a conclusive relationship between mask ⁄ respirator use and protection against influenza infection.

Penetration of:
Cloth masks by particles — 97%
Medical masks — 44%,
3M Vflex 9105 N95 — 0.1%
3M 9320 N95 — <0.01%
Cloth masks resulted in significantly higher rates of infection than medical masks, and also performed worse than the control arm some of whom may have worn masks.
The virus may survive on the surface of the face masks
Self-contamination through repeated use and improper doffing is possible. A contaminated cloth mask may transfer pathogen from the mask to the bare hands of the wearer.
Moisture retention, reuse of cloth masks, and poor filtration may result in increased risk of infection.
Cloth masks should not be recommended for health care workers, particularly in high-risk situations.
There is a key difference here between the population level mask wearing (ineffective cloth masks improperly warn, touched frequently, and not disinfected between uses), and more targeted, short term mask wearing.
There are dozeons more of the above studies by the way.
The evidence fits into four categories:
1. Observation studies that sometimes show substantial (very large) reduction in droplet spread when masks are worn
2. High quality randomized controlled studies in the real world which show zero to negative effects of masks in actual infections with cold or influenza
3. First wave data which correlates early mask wearing with lower total death. Absolutely useless since this was winter and I agree masks help in winter, and also absolutely useless because the governments that mandated masks early were the same ones who locked down early (i.e. they ignored the cuck Western experts/WHO and did what made sense early and well).
4. Second wave data (now) from Europe which shows mask wearing has had no measurable impact on the rate of increase of transmissions. Data from all US counties which shows no correlation between mask wearing and infections, hospitalizations or deaths.
The Europe sitaution is an excellent demonstration of the problems of (3) - data which led the CDC and WHO to change their position on masks. If you ran the same comparisons from the last 3 months on mask wearing vs infections and deaths, you'd conclude that masks cause corona! Such is the nature of drawing conclusions from biased data. But scientists are mostly brain dead (especially in epidemiology) so the data bias from the first wave change WHO/CDC recommendations.
Overall the data is strongly against population mask wearing doing any good.
