It's not a coincidence. He's describing trends as he sees them. He's a member of the WEF, so of course he's going to do that.
No, that's bollocks. For a very small minority of people-- those with severe unrelated respiratory restrictions, for instance-- they can (rarely) cause complications; but those people are exempt.
For the vast majority of uninfected or asymptomatic people, masks are still beneficial. They still reduce the risk. The primary vector of transmission for the coronavirus is water droplets, and those droplets can remain airborne; so if those droplets land on a mask, rather than directly onto your face, then the risk of infection is lower.
This is all well established science that's been proven time and time again, and has been widely recognised long before the pandemic.
They're a "symbol" solely of one's willingness to adapt their own behaviour to protect those around them.
Think of it this way: if the shadowy cabal wanted to control us, why would they want us all to be wearing masks, making us harder to identify and harder to recognise on CCTV?
