It's a step up from being replaced by: Catwoman, his predecessor Tim Drake, Duke Thomas, and Harley Quinn. All of whom have replaced him already in the main continuity as has been pointed out in SS and AoSS, and most of whom replaced him in Injustice. At this point, Damian's been shown in multiple books accepting that Bruce doesn't give a damn about him and has moved out to live on his own at the ripe old age of thirteen.
I don't see him having a problem being released by a mind controlling starfish. If it makes Bruce happy than Damian doesn't complain or interfere regardless of how it impacts him. And it's an animal. He likes animals more than people.
