If Apple was worried about this, they shouldn't have flaunted the court order in a way that made the judge say in the subsequent order that "this is an injunction, not a negotiation."
I am worried that now game companies are incentivized to abandon "initial purchase" games/apps and go the "loot-box, subscription" route.
Is this the final nail in the pay one time for games coffin?
No, these will continue to be made. Just that the Premium iOS Games market will also stay much smaller than the IAP horror world the rest is.
