Even Netflix mostly funds their own content. A “Netflix for games” would involve Google funding exclusive games to be made for their platform.
Stadia had their own first party games that they canceled rather early - Feb 2021, year and two/three months after launch. The writing was on the wall. Stadia was a failure through and through, and they knew it.
Well, the current situation is that stadia is defunct, because their business model doesn't work!
I'm saying that i reckon an alternative business model such as a subscription service for games would've worked, but require much more up front investments. Epic games have managed to attract a large dev following using incentives like grants (in exchange for exclusivity). Google's pockets is much deeper than Epic; obviously, google isn't really ready to invest in the stadia platform or make it succeed commercially - it's likely no more than a technology demonstration, something that someone at google intended to further their careers (like all things cancelled at google).
The branding of google services is highly tarnished by now. If you are a business, you will not purchase any google services, short of the monopoly on advertising.
