Yeah like the Google Stadia. I think there was news of someone who spent >100s of hours on Red Dead Redemption 2 only to have all his save data wiped when Stadia shut down.
Edit: Looks like Rockstar did the guy a favour and it was 6000 hours (https://www.nme.com/news/red-dead-redemption-2-stadia-player...)
Google Stadia was always doomed to fail because people have zero trust in Google keeping a service alive if it's not an immediate success.
This is from 2019: https://arstechnica.com/gaming/2019/11/stadia-launch-dev-the...

The stupid thing with Stadia is that every game you bought came with UNLIMITED FREE 1080p streaming.
They certainly made a loss on this guy but it is far from "stupid" from a consumer perspective.
Youtube comes with "free 1080p" infinite streaming and it makes double digit billions a year.
You can't be interrupted with ads every few minutes when gaming.
You absolutely could though. They could just pause the game in a solo game or detect you are in between matches in a multiplayer game.
File serving is cheap vs rendering a game. A single core can serve many video streams but may be insufficient to run even one game.
