I don't think this (or these) list(s) are aiming to shame MS (or Google) for shutting down products, only to catalog and preserve the history.
Microsoft is a polar opposite: they kill unpopular things, monetize popular things, and provide ridiculously long support (and backwards compatibility).
The subpar game library is another.
That's one flimsy ass lawsuit. Upscaled 4K for some titles ( admitted by Google themselves) is still 4K.
For the game library, did Google promise they'll have every game on it? What promise was broken? They worked with game developers directly, paying to get games ported ( be it indie or Ubisoft/EA/Rockstar). They should have done more, but it's not like Stadia was advertised as "the platform you can play all games on" and then it turned out you only have 20 games.
