I want freedom. Offer both so everyone can pick the model that best matches their usage pattern. A GamePass+GeForceNow combo is nice if you want to play a diverse library of games without having to install terrabytes of game data. Also if you only want to play stuff a short while (hello ADHD), a subscription might be better than full price.
But again: freedom. I don't want to be forced into subscriptions but neither would I want someone to forbid me from subscribing.
