If they had competent management who knew that things like this were an investment they would take the time go use it, gain market share, and slowly build up their library. Over time a streaming service like that on youtube could be huge in the market.
Unfortunately they are so hyper capitalistic if it's not profitable within the first quarter they'll start talking about axing it.
Their strategy did not make sense at all. They wanted to make a game streaming service yet they were acquiring a bunch of game studios... To the contrary of GeForce NOW, its arch competitor, Stadia forced you to purchase games that were only playable within the service in its store. It is a complete shit show.
Ironically, if they had just outlined their eventual plan for what they would do in the event that the service was ever shut down I think more people would have been willing to try it. At least some portion of potential users chose not to use the service because they thought it likely Stadia would eventually get shut down and the money they spent on those games would just be lost. But at the end of the service, the users basically got refunded for everything.
