From my experiences, most people are doing what they think is right. We should take more time understanding why people think what they are doing is right, even when we may perceive the action as immoral or wrong.
Morals matter even when they are inconvenient.
One of their discussion was on how much commitment was crucial in the game dev world. Devs on all sides (platform, libraries, actual game) would put their skin in the game and gamble time and money but also personal energy to make something successful, and there was an expectation that all participant would stick together even as the future gets bleaker (what comes to my mind is Nintendo supporting and pushing the Wii U for a while, even as it was a clear failure, or Sony keeping the Vita alive as much as they could)
Your reputation as a platform maker gets a serious hit if you're ready to quit the minute your forecast gets dark, and game devs never really forget this kind of things, unlike other more opportunistic ecosystems.
I kinda hope the Stadia team could move on outside of Google to a more fitting company..
So this does make a lot of sense. Huge time commitment for deliverables + ultra specialist roles and expertise = the important industry people have long memories.
If you say, both to the public and to the team, that you might shut down but you're not sure yet, that's as good as shutting down. And if there are rumors about shutting down, because it's close to happening, then you may have to address it. And you may believe that the only chance you have of not shutting down is to tell everyone that you aren't shutting down.
