All the comic book idea bashing aside, actually no one really takes these "expended storyline" Dark Horse stuff seriously, no matter what kind of franchise are we talking about. Most of us here doesn't really care about Matt Reeves' thing either. What you wrote that's what is canon, so from artistic POV don't let this stuff bring you down.
From the copyright/financial angle, screw 'em, such is life (seems like not just in the far west).
This doesn't make you a fool.
And we danced, on the brink of an unknown future, to an echo from a vanished past.
