Go on a number of the gaming subreddit and you’ll see Stadia is being met with distaste and hesitation. Gamers are increasingly tiring of the games-as-a-service model, and this is a step even further in that direction.

Go into gaming related subreddits, even for beloved and succesfull games and products - and marvel at the toxicity and negativity you'll likely see all over the place.
