Ah, my bad. I misread the paragraph in ISWG about that. It's not that their power is lessened, it's that, due to a lack of agents in the area, celestials and fiends can use it as neutral territory for negotiations.

Rahadoum’s enduring atheistic nature has had another, invisible side effect. Outsider servitors of gods use Azir as a neutral ground. The gods certainly watch their dealings there, but without open followers on the ground, the gods lack agents to enact their agendas, leaving room for plain negotiations. Many unexplained supernatural effects that occur within the cities of Rahadoum are due to invisible conflicts between celestials and fiends.
