Stadia has been a godsend for me, my family and friends. One of the lesser known features of Stadia is that it is similar to Netflix in its account management.
You can have 4 family members and your games will be available to all.
This allows me to share my library with my siblings and close friends. They can play all my games and I can play all their games. This pushed me to play games I would never have explored otherwise. I am lucky to have a high income and guilty of purchasing games on impulse (as my Steam library can attest). For the first time, my "sleeping" games are useful to the people I love.
It also makes "lan" nights very easy. In fact, with Stadia, I had my first such experience in decades. I can play on my phone with a controller, someone else on the living room TV and someone else on a MacBook Air (which is huge as gaming on that platform is simply not a thing without streaming).
Just about anywhere and at anytime without the need to plan anything.
My partner's GPU also died recently and with the current market prices, they had been playing console exclusively. I gave them access to Stadia and they have switched to playing Stadia exclusively.
Even on wi-fi with a group of 4, we are still competitive in shooters and racing games. In fact, other than issues regarding my own network, I have not experienced lag or glitches from Stadia's side of things.
Stadia dying would be a very sad day for my circle of friend and judging by all the 2-4 members groups I see in games, we would not be alone in that.
