The analogy is pretty exact:
Disabled people do have a choice to take it or not (they are not forced), so they have an opportunity to use benefit.
As the "disabled" (that why I came wiith that analogy at first place :D) players who have stoped playing, Gree gave them an opportunity to have an benefit of comeback.
They have an opportunity! So if they hate the game they won't use it anyway, whenever how huge it woud be, right?
And here we are having people angry about that, because they want those bonuses too?
"We are playing their game we should be treated like favorite children but they give cookies to other who abandoned them"
That's just spoiled children's greed, sorry.
