From what I gather Epic delisted various of their Unreal Tournament games across all stores a couple years ago due to them not supporting their modern online services (including chat). This was within days of being fined $500m for, among other things, allowing on-by-default text chat in one of their other games that is available for children/teens to play, so some believe they'd rather delist than update some of their older games.
