> Taking the case of Photoshop vs. Gimp - I don't think the problem is complexity, lol. It's having to relearn everything once you're used to photoshop. (Conversely, I've never shelled out for Adobe products, and now don't want to have to relearn how to edit images in photoshop or illustrator)
I don't think this comparison is really accurate, Adobe's suite is designed for professionals that are working in the program for hours daily (e.g., ~1000 hours annually for a creative professional). There are probably some power users of The GIMP that hit similar numbers, but Creative Cloud has ~35-40 million subscribers, these are entirely different programs for entirely different classes of users.
