Disinformation is peddled for a variety of motives. The Russian government employs disinformation as part of their expansionist geopolitical aims. The Chinese Communist Party uses it to further entrench their political authority and grow their global influence. Professional influence operators do so as guns for hire on behalf of powerful industries, ranging from oil to tobacco companies. Trolls on 4chan often do it in service of pure nihilism.
But by far the most common and compelling motivation to spread online disinformation is profit.
