I have wondered that myself. Perhaps not a loss-leader per se, but definitely willing to take more of a hit on margins for the camera in lieu of (presumably) healthy margins on film packs, than anyone attempting to sell a 35mm camera these days. It may explain the lack of a middle-weight affordable option.
Or just maybe an electronically controlled leaf shutter costs a lot more these days when they're only being made in the 1000s, rather than millions as would have been the case throughout the 1980s and 1990s?
