From the perspective of knowledge equals power, intentional misinformation, no matter by whom, could be regarded as abuse of power.

More people should educate those knowing less instead of ridiculing their ignorance. (Given the "knowing" really "know", but that's another topic.)

Edit: Intentional misinformation meaning posting and spreading "fake news", willfully publishing or sharing false information through media of any kind, as organization or individual, not merely everyday lyingy which is sth different.

Edit 2: Apparently it's "misinformation" not "disinformation" sorry.
