My contention is that people jump to "It's just a bot" when they parrot obvious government propaganda they disagree with, when the average person is as likely to parrot obvious propaganda without involving computers at all.
People are just generally stupid by themselves, and reducing it to "Robots be robotting" doesn't feel very helpful when there is an actual problem to address.
It isn't an entirely new concept or unknown, and that isn't what is happening here. You're making a lot of weird assumptions, especially given the fact that the US government wrote several hundred pages about this exact topic years ago.
You literally claimed "when you have accounts with these stats, and they say these specific things, it isn't difficult to guess..." which ends with "that they're bots" I'm guessing. Read around in this very submission for more examples of people doing "the jump".
I'm not saying there isn't any "foreign misinformation campaigns on the web", so not sure who is projecting here.
