They are trying to gaslight us. Foreign powers want to misinform and distract the public in democracies; a misinformed populace puts pressure on elected governments to govern poorly. If democratic governments flounder because of this, that gives authoritarians an opportunity to get more power and influence over world politics.

Not to say that western nations aren't engaged in their own information operations. Just that it is asymmetric warfare, authoritarian regimes have a lot less to fear from a misinformed or disengaged public.
