^Jumping to a conclusion is not okay when it contradicts virtually everything we know about
Star Trek time travel. The future in the Trek universe
is mutable. It's
very mutable. I've given you the overwhelming in-story evidence that that's the case, and I've given you the real-world explanation why the storytellers adopted that policy. (That's what I mean by "real-world common sense." I'm not talking about the imaginary time-travel rules used within the fiction, but about the real-world reasons why it's sensible for writers in a shared fictional universe to favor a mutable future over a rigid one, because the latter would be too restrictive on their own or others' future storytelling choices.)
No, those stories you've narrowly fixated on (while ignoring quite a few others) do not blatantly contradict each other, but that does not even begin to prove that they
couldn't be in separate timelines, or that the future can't change, especially when we have plenty of
other evidence that it can and does change. Absence of evidence is not evidence of absence.
On top of everything else, you're making some rather rigid assumptions about the particular situation presented in
Hive without even having read the whole story. At the very least, you should wait to get all the facts before you draw any conclusions. This whole conversation is premature.
