Given the ambient conditions in many churches (poor humidity control, for instance), the resistance to spend on regular maintenance, and the level of general ignorance among church decision makers about the piano as a machine, switching to a digital can make very good sense.
I couldn't disagree more. Having a good acoustic instrument will attract better a better player/players which ultimately helps fill the seats and thus brings in more money. The price of upkeep for the first few years is cheaper on a digital, but they have a much shorter lifespan, especially in a busy church.
