In other words, there are a bunch of people whose job it is to keep the enemies of their country in mask denialism and maximum COVID infection as deeply as possible, and it's primarily done through social media.
And while it's useful in a sense to put forth such intentions while knowingly coordinating bot networks and the like, it's social engineering that does the heavy lifting: the real effectiveness comes in ways you can't directly control, when people soak up the information around them and begin propagating your message (or weird mutations of it) on their own initiative, thinking they've invented it.
And that's how they getcha. So I'm not the slightest bit impressed or surprised to see spring 2020 memes persisting: they're being fed, on purpose, singlemindedly. I confess to being surprised when the same memes turned up in English in various EU countries, but when the job is to propagate the message, I guess English signs in foreign countries is all part of the game, indeed a normal part of anybody trying to send messages to the West.
