I'm not sure if their strategy ever changed along the way, but when Stadia was first announced, it was a purely cloud gaming platform where you still needed to buy a license for every game. Not knowing what would happen to my purchased games was the main thing keeping me from trying Stadia - I'd have been happy to use it if it was a Netflix / Xbox Game Pass style service where you pay a flat monthly rate for access to a library, or if it was clear that any games you bought would be refunded if the service suddenly shut down.

As it was though, it seemed as though you could drop a ton of money on Stadia games, and Google might pull the plug the very next day, and you lose everything you just purchased. That worry was the deciding factor for me to never give Stadia a go.
