it is ancient greek, well biblical anyway...

disinformation and other forms of propaganda have been around for ever, just as have people who will believe anything they read/hear/see

what is different now is that it can be leveraged in such a powerful way on platforms that many rely on for other perfectly legitimate reasons

it is down to the platforms, but it seems to me they view this sort of thing, as well as actual abuse up to a point, as colateral damage in the persuit of ideological 'freedom' and of course $$$
