March 2020:

U.S. health officials say Americans shouldn’t wear face masks to prevent coronavirus https://www.marketwatch.com/story/the-cdc-says-americans-don...

In fact the U.S. surgeon general recently urged the public to “STOP BUYING MASKS!” “They are NOT effective in preventing general public from catching #Coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!,” wrote Surgeon General Jerome Adams on Twitter.

The CDC said last month it doesn’t recommend people use face masks, making the announcement on the same day that first case of person-to-person transmission of coronavirus was reported in the U.S. The CDC recommendation on masks stands, a spokesman told MarketWatch Wednesday, even with the first reported case of a COVID-19 infection in an individual in California who had not been to China or been exposed to a person diagnosed with the virus.

“The virus is not spreading in the general community,” Dr. Nancy Messonnier, director of the Center for the National Center for Immunization and Respiratory Diseases, said in a Jan. 30 briefing. “We don’t routinely recommend the use of face masks by the public to prevent respiratory illness. And we certainly are not recommending that at this time for this new virus.”

WHO stands by recommendation to not wear masks if you are not sick or not caring for someone who is sick https://www.cnn.com/2020/03/30/world/coronavirus-who-masks-r...

“There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit. In fact, there’s some evidence to suggest the opposite in the misuse of wearing a mask properly or fitting it properly,” Dr. Mike Ryan, executive director of the WHO health emergencies program, said at a media briefing in Geneva, Switzerland, on Monday.

So, you linked a number of articles from early 2020, when there was not significant community spread of COVID and thus the primary strategy for dealing with it was isolating and quarantining individual cases, and most people in the country would probably not come in to contact with someone carrying COVID.

If you want to know what the WHO recommends, you need only look at their website:

"Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal of masks are essential to make them as effective as possible."

The CDC made that statement because masks work. It was worded dumbly, but they're just saying that when the mask supply is constrained, healthcare workers should be prioritized over the general public. If masks didn't work, there'd be no point in triaging who gets them.
