There is a general idleness and complacency of thought that assumes any picture made with a camera, even a smartphone, at the front end of the picture-making process is a photograph.
Most casual references to digital pictures as photographs are not motivated by fraud but are a product of ignorance. It's just another of those cultural deceptions that are so widespread and familiar that they largely pass beneath care or notice; except perhaps at APUG.
The unique thing about photography isn't cameras or lookable pictures made and displayed any old how. It is that photographs are generated exclusively from light-sensitive materials and as a consequence their authority to describe subject matter comes not from resemblance but from direct physical causation.
