"Misinformation" might (sometimes) be a synonym for "wrong".... but "whataboutism", "disinformation", "malinformation" are not. They mean different things.
Disinformation actually does mean wrong. But it also is an accusation of maliciousness. That's the distinguishing feature between misinformation and disinformation: intent and prior knowledge. But with the other two I agree. Whataboutism is non-sequitur arguments. Malinformation is cherry-picking data with intent to deceive.
