It is though; honestly, it has to do with how the community interprets the leak. At first, everyone fallaciously regarded it as objective fact, so it was fact in that context. Now everyone fallaciously regards it as thoroughly refuted... so it is, or it is here. We obviously need to wait for further news until people get on their knees and crawl back to Sal and his source.
No reasoning is enough. It is "good enough" to be fact by their standards. Even if you point out that that sentiment is utterly arbitrary, they retort with, "it has not been wrong yet." The opposite will become true. "It is false, Chrom is not playable." You might assert, that does not definitively contest the leak in its entirety; however, they will retort with, "it has already been wrong once." This is; of course, despite the notion that they blatantly disregarded overt contradictions as a result of confirmation bias in the first place.
Tl;dr: Gematsu supporters are incompetent and Gematsu detractors are incompetent. One has to realize that the leaker DOES have insider information. The question is... to what extent and is it relevant as of current. No one asks that though because they forget that the leak alludes to information prior to roster finalization, thus they erroneously assume that the leak needs to be either completely real or completely false. It is overt that that is a logical fallacy. GG.
