The difference is in simplifying the UI versus taking features away. The former is perfectly fine, the best UIs (in my opinion) don’t exist/are perfectly invisible. However, taking features away in order to ‘simplify the UI’ is the wrong approach – making these features accessible in such a way that they don’t clutter the UI, preferably sorted/ranked by frequency of usage certainly is superior to dropping them. That's why Emacs has M-x/M-:, menus were invented, every sane desktop environment has some way to bring up a programme by its name and human-readable configuration files were invented: Such that the most obvious parts of the UI can offer the most frequently used features and all other, less-frequently used but still necessary, features are accessible in some way.
