I disagree with the "misinformation" label generally. But I can see with voting or public health how there is a public interest in people receiving correct information (ignoring that authorities have lost all credibility on the larger anyway).
But when it comes to politics, or "science" if we insist on calling it that, an official narrative is counterproductive and everyone has a right to say what they want, even if it's "wrong" or you don't agree. TMZ may be a source of celebrity misinformation. Who cares.
