I've seen multiple things be deprecated while at Google and I can say that the things I saw killed from the inside (because it was a product I worked on) in the past 5 years were either not being used by many users anymore or had an alternative that had similar features instead. So if you depended on it, you could depend on something else. And if it was successful, it wasn't canceled. I didn't work on Stadia but I imagine that it was a huge waste of money for the company for the relatively few users it had. If they could have offered a good subscription based service like Xbox Game Pass or Apple Arcade I'm sure it would have more users. But getting access to content would be very expensive. At least they refunded consumers' money for the games they purchased.
