Digital has a lot of advantages, but simplicity is not always one of them.
I think on this topic, in particular, the marketing and common usage of saying "crop factor increases focal length" or calling it the "focal length multiplier" has done a disservice and added a lot of confusion.
If it were presented solely as "crop factor" meaning you take a 35mm picture then divide the length and width by the crop factor (making a smaller picture for DX or a larger picture for medium format) it would avoid the whole focal length confusion. The focal length stays the same.
