Yeah, except for all those aliens who actually go outside and see for themselves, or ask people who have been there. You know, like most of humanity would do. :D
I get the article's premise but it sounds like a non-issue midterm. A lot of people go through increased financial hardship currently, and their interest in news is waning so the whole thing kind of balances itself out: more manipulated online material, less engagement from people. I'd think the latter factor will prevail because the manipulated material is put online to achieve a goal (usually a financial one) and if that goal is not achieved then the manipulators will start losing interest -- eventually.
Though I am really curious to see how will the whole thing unfold in reality. Obviously I am not claiming I can predict the future.
