Even if some speech is known to be false (insofar as your epistemology allows), it should be criticized and proven to be false by more speech, not silenced through censorship.
In any case, I'm still baffled by how you think you've articulated logic that can supports that they "didn't put their finger on the scale". Obviously they did, obviously they knew they did. What other reason could they have for doing it? If your principle were instead "they should put their finger on the scale when opposing actors intentionally spreading false information" at least you'd be consistent.
Though then the irony of this whole thing is that the story was true the whole time.
