Why does the scientific consensus on masks keep flip-flopping?

the general consensus is that people should wear masks but that we dont have enough to go around for people in hospitals so they are being asked to not. (which is counter productive in a way considering that many people already have a bunch and its unlikely they will donate them)

Not enough masks in canada for everyone to wear them. They need all the masks for people working in health care.

Obviously you should wear a mask. they are counting on everybody everywhere in the country to cover their mouth when they cough or sneeze.

Would you drive a car without airbags and leave you safety in the hands of other drivers on the road?

Good luck getting masks at this point though. I'm sure soon they will start telling people to make their own.
