No one is trying to rewrite history, who owned warp3D a decade ago is irrelevant to its current status, which is, it is not a Hyperion product and it is not dead.
what does that even mean?
That makes no sense, ofcourse some one can invest in one technology even though an other is announced. Warp3D has been a big item on many AOS4's wishlist, surely making that come to life, could be reason enough.
I am not saying anything about the current state of AOS4.2 or Gallium, I am just saying, that speculating on AOS4.2's failure to deliver based on new Warp3D drivers being released, is reading to much into it.
Regarding Gutjahr read the newest blog of Trevor (expecially the "Troll" part)
It was already my guess when update of Warp3D was announced (I even predicted that at that time). It makes most sense if you have some insight view and know that 4.2 will not be available in foreseeable future and want to have Warp3D as a kind of quick solution. Otherwise it would be wasting money and I do not think that Trevor would do that. But it is of course just speculation. We cannot know and those who know propably are not allowed to speak

. It is not a guess if 4.2 will be ever reality or not but that 4.2 is still far away.
