When I go out, I see lots of people wearing masks. I also see medical

The BBC was unequivocal, at the start of this crisis, in stating that
masks are not useful as a preventive measure against COVID-19.

Was the BBC wrong, or lying? I don't recall seeing/hearing any
official retraction of the previously stated position.

You mean this:

Seems to explain when you need them and when not.

Although the latest reports seem to be showing that the risk of direct
inhalation of droplets from far greater distances than 2m is a lot
higher than was first thought, so although the rest is right, wearing a
mask may provide more protection than was first thought.
