I was pretty taken aback by that, they go way further than disappointing about not having the game on their platform of choice, to just outright yelling at the developer for somehow this being their fault?
I think this is just a case of very vocal minority.
Who reasonable is exited about Stadia anyways? I don't think it will last till next year without being slashed by google.
I wager 18 months.
As if you could create a big impact game from (or near) scratch in a year xD
