Wait, it’s upside-down? The picture I saw wasn’t updside-down…I don’t think.
If it’s upside-down that’s a different story because that’s not the ok symbol.
I assumed the article you linked explained, but I didn’t check.
I looked at a few articles, the one picture I remembered wasn’t with the upside-down hand gesture for some reason. But in the article I posted, you’re right.
