I think Google's biggest flaw in this regard is their own denial of the pattern of shutting things down. If they just acknowledge that's how things go, they can prepare better off-ramps for people who adopted their product. Doing this to your users is a slap in the face because it shows no gratitude for the fact that those people took a chance on your product. They believed in it, and it's not their fault your project failed. Why should they suffer?

But because of Google's hubris, they seem to never admit that failure is an option. Of course they shouldn't say it publicly, but they should have much better internal plans in place for euthanizing products humanely. Failure to do so repeatedly, on a scale like this, reeks of organizational dysfunction, and the absence a moral compass.

I was not a Stadia user, but events like this reinforce my motivation to drop all the Google products I possibly can before they drop me.
