I don't know. The quality and reliability of Google's products have been on a steady decline for years. One of the largest HN threads of all time is about the decline of Google's search product. Stadia failed because of mismanagement. Google doesn't appear to innovate a lot these days.
This is mostly due to incentive and mismanagement issues at the Senior level at Google, instead of engineering deficiencies in the median Googler. Google's search is getting worse for users because it's getting better at making profit, and Stadia is failing because of mismanagement as you say, not engineering quality which was by all accounts excellent.
