Cube Cutscene: Two Different "Voices"?
This is just some general, very loose speculation I've had in following the Philip K. Dick rabbit hole, (mostly) nothing concrete.
The cube is covered in a QR code-encrypted message.
During the cube cutscene, the lifepath taglines: NO FUTURE, TRUST NO ONE, and TURN BACK are projected directly onto our field of view.
If both messages come from the same source, why the two different media of transmission?
Why doesn't the cube just project its message at us like the taglines?

I'm fully on the "Philip K. Dick is the key to FF:06:B5" train. So many of his works are absolutely influencing the mysterious aspects of Cyberpunk 2077.
As we know, the magenta moon is very much a VALIS reference. VALIS is magenta, and is a force of good, and beams its information directly to Horselover Fat (a PKD analog), and this is how it was projected to PKD in his Exegesis.
To me, this pushes the taglines into the Good/VALIS/Truth corner, since they are directly sent to the player.
Philip K. Dick also had a recurring character archetype: Palmer Eldritch, Jory from Ubik, President Ferris Freemont, who he described as "...an evil magician deity [that] is in control of our world and heads." These beings represent a kind of entropic-demiurgic trickster god of corruption, and their presence often leads to degraded, increasingly capitalistic/transactional, technological/artificial "dead" worlds in PKD's stories.
I think Gaunter O'Dimm is another expression of this character archetype in the CDPR multiverse. And I suspect the cube and its message is from this side of the conflict.
My interpretation is that the difference in communcation media stems from VALIS not being bound by the material world, and the Palmer/Gaunter/Demiurge being bound by the material world or dead matter?

TL;DR: I think the cube and the moon are both talking to us in the cube cutscene, and the cube is badwrong.
