I suspect that most people who are willing to the simulation hypothesis seriously would be somewhat open to the idea of "God" in the very broad sense of some intelligent and powerful agent or agents that exist outside our current scientific understanding, but still not open to some specific idea of "God" in some specific organized religion like Christianity. The analogy would be some extremely specific hypothesis, like that our Universe is being simulated by a quantum computer built by Peter Shor in his basement in 1995.
