I'm not sure if this model is going to be sustainable. Games as service and the proliferation of suscriptions will eventually burn people out, not everyone has enough money to pay for all the subscription entertainment demands nowadays. The fact that, after years of paying for stuff you still don't own anything is just the cherry on top.
I don't see hw that applies here or maybe you are mixing up the whole GAS thing.
This is sony revenue generated from services such as PSN....etc. So basically even sales on the PS store count towards this along with PS subscriptions.
All that is very different from GAS. And as for subscriptions, sony is obviously against multiple subscriptions existing on their platform. Its why we dont have EA access.
