It’s when you disagree with me.

I don't trust big tech to regulate truth, but let's not dismiss misinformation with such broad strokes.

There are deliberate attempts by politically and monetarily motivated groups to spread objectively false propaganda. FUD/HODL to mislead investors, conspiracy theories to sway public opinion, pseudoscience to peddle ineffective medical treatments... The people doing this effectively aren't individuals disagreeing with mainstream discourse, they know exactly what they're doing.

According to Wikipedia: "Misinformation is incorrect or misleading information presented as fact. It is differentiated from disinformation, which is deliberately deceptive."
