In the US, they flip flop every week, its just political to keep everything locked down until November election.
I'm fine with people choosing to wear them or not, I'm fine with governments recommending them, I'm fine with Trump wearing them, whatever. I would never attack a person for making that kind of choice. I don't even have huge objections to mandating them in public transport, since you also have the option to walk, cycle, drive a car. And airplanes, because you can't have a socially distanced plane while running a profit.
But what's happening now is governments are mandating them even in places where it's not germane to the situation. And openly encouraging vigilante enforcement by left-wing hate mobs, because you can't expect police and shopkeepers to confront people all day, but the government still wants to enforce the rules. It's a one-way road to social control. I would be very surprised if jurisdictions that are forcing masks now are ever going to rescind the mandates, except maybe some red states in the US.
Even the flu comparisons are dangerous. Governments might as well say: "Oh yeah you're right, we're going to mandate masks forever just to keep down flu deaths as well".
