As for your last point, Solzhenitzyn said something memorable about that -
'We know that they are lying, they know that they are lying, they even know that we know they are lying, we also know that they know we know they are lying too, they of course know that we certainly know they know we know they are lying too as well, but they are still lying.
In our country, the lie has become not just moral category, but the pillar industry of this country.'
That's not true. Old-school disinformation platforms like TV, bought political parties, etc., worked and still work fine for disinformation and division. If you're not familiar with the subject, you'd be surprised just how inventive these campaigns can be.
