You kinda alluded to this, and kinda got the wrong conclusion, but when a game developer releases a complete game, and then after fixing some patches, it moves on to other things, no one claims that they "bailed out" on the game. Do you think Valve "bailed out" on HL:Alyx? It just makes no sense. Earth VR and Tilt Brush are pretty complete apps, not everything needs to be worked on forever. At some point you get diminishing return and start wasting your time.
