A weapon that is not controlled by any government is just a not-government-controlled weapon.
But I disagree with the "weapon" classification entirely, because highlighting an issue is the best a subtle influence campaign can achieve, unless Jedi mind tricks are real. And if people don't agree that the issue being highlighted to them is worthy of their attention, even such attempts will fall on deaf ears.
And an article attempting to highlight the issue is not comparable to the kinds of subtle influence the CCP may try to exert over American opinion through TikTok. I don't think there is evidence of that yet, but I also don't see a good argument for waiting around to find out.
