whom do you think they were always recommended? Because that absolutely hasn't been true for the WHO and CDC, as the links I already gave you show. The WHO has changed its position on masks, and has been in conflict with the CDC on the same topic.
That video you linked to doesn't in any way disagree with anything I've said, nor rebut the point. In fact it supports it. It's just a video of Anthony Fauci talking about why he changed his position on masks: without admitting to it directly, he 'explains' that he wanted to ensure medical workers had access to them. But he is on record as having recommended against masks in the past. Here's Snopes saying so:

In the March 2020 clip, Fauci said: “Right now in the United States people SHOULD NOT BE walking around with masks … You should think of healthcare providers who are needing them and the people who are ill.” (my caps)

He also acknowledged that masks were initially NOT RECOMMENDED to the general public so that first responders wouldn’t feel the strain of a shortage of PPE. (my caps)
Now many countries have introduced face mask requirements (which is dumb, but clearly a change of position).
Not only has mask advice changed but it's changed for dumb reasons: there's no scientific evidence masks work to stop SARS-CoV-2 transmission, especially not the cloth masks being actually deployed. This article investigates what's really known about this tactic:
