I don't understand not caring about it, even were I not working on it. I was having discussions with friends in 2015/early 2016 where we were looking at stuff and it was obvious what was going on. The day after the election, Zuckerberg was saying it is "crazy" that Russians could have been involved.
We've got something systematically wrong if the biggest tech companies in the world with all the data and resources either were oblivious to it (seems likely based on their reactions) or were aware of it but kept doing it because it made them money. By all accounts their ad tools actually made this especially easy.
No country, much less one that considers itself a superpower should be willingly letting a foreign nation spread propaganda. That big moat called the Atlantic and all those resources don't matter if you you're gonna let them in the back door. This kind of naivety/ignorance is too common in the power centers of the US. Consider Obama getting outwitted by Putin and Clinton getting beat by an idiot like Trump. Maybe they aren't so clever after all.
That Russia is doing that is annoying, what's offensive is that our leaders allowed it to happen, and what's disturbing is people either acting like it hasn't happened (evidence says otherwise) or just want to shrug it off. It's hard to say how much of the recent domestic unrest is being fueled by it.
