Artistic Credit Assignment: Using Cameras vs. Using GenAI Models

Very curious about the credit assignment practices in our society. Usually photograph credits are assigned to the photographer who took the picture instead of Canon or Nikon. In contrast, when a picture produced by a human prompting the GenAI models, credit is usually assigned to the model making company such as Midjourney, DallE or Stability. What is governing this behavior? Or did photography also go through a moment where camera companies got the credit for the pictures produced?
