I know most of the comments here are focusing on "Google shuts down yet another thing as everybody expected" but this is really doing right by consumers.
I think they deserve a lot of credit here. With so many (usually valid) warnings about how you don't really own digital content in the cloud or hardware you can't root... the fact they're giving everyone all their money back even when they're probably not contractually obligated to, that's pretty huge.
If Stadia were a startup that ran out of money/funding, that would never happen because there wouldn't be any money left in the first place. So even if Google cancels a lot of things, this is a nice (if occasional) bright spot of news, that Google has the ability to do full refunds and actually does it.
It also makes you wonder what future gaming plans they have, especially since they're spending the cash to preserve as much goodwill here as possible.
