I don't know. On the flip side, I think it's misleading and potentially confusing when some folks deliberately misrepresent what the show is actually saying by asserting the opposite as though it's established fact.
It's like asserting that, contrary to what the movie said, that Norman Bates wasn't really the killer in PSYCHO. And not as some cool, alternative "head canon," but as an actual description of the plot of that movie.
For better or for worse, the new shows are meant to be set in the Prime Universe, so when I see folks telling other people, who may be confused on this point, that "no, it's set in the Kelvin universe" or "no, it's set in an alternative timeline," that's just misleading people -- because that is explicitly not the intent.
(We can debate how well that intent is being executed, but let's not pretend that the Pike on SNW is explicitly meant to be the same character, in the same universe, as the one from "The Cage.")
