I wonder if Apple discontinued aperture because the number of potential users is so high? Everyone who buys an iPhone is a photographer, and their consumer solution for them is the photos app. They want to dumb everything down and make it more streamlined, so all your photos just sync via the photos app to icloud and there’s no work involved like cataloging or organizing. You can make all your basic exposure and color edits right in the camera or photos app.

Positioning aperture alongside final cut and logic, as the power tool for cool creative professionals, would confuse that because of how big photography is for the iPhone.

Edit: also come to think of it, aperture was almost exclusively a tool for managing your photos shot on a dslr. Apple just wants everything to be “shot on iPhone” now so you shouldn’t need that type of legacy workflow.
