The various health authorities told people not to use masks at first because:
Hospitals were in danger of running out of protective equipment.
The public was panic buying anything and everything. Remember empty grocery store shelves? Price gouging people who were hoarding all the hand sanitizer?
When those circumstances changed, so did the advice.
There's no one on earth who gets everything right first time, and thus never needs to change their mind. Not one single person.
Why do you value an opinion or advice that never changes?
