Well, yes, but that observation doesn't prove the point you think it does.

People who were highly experienced with previous non-ribbon versions of Office, disliked the ribbon, because the ribbon is essentially a "tutorial mode" for Office.

The ribbon reduces cognitive load on people unfamiliar with Office, by boiling down the use of Office apps to a set of primary user-stories (these becoming the app's ribbon's tabs), and then preferentially exposing the most-commonly-desired features one might want to engage with during each of these user stories, as bigger, friendlier, more self-describing buttons and dropdowns under each of these user-story tabs.

The Ribbon works great as a discovery mechanism for functionality. If an app's toplevel menu is like the index in a reference book, then an app Ribbon is like a set of Getting Started guides.

But a Ribbon does nothing to accelerate the usage of an app for people who've already come to grips with the app, and so already knew where things were in the app's top-level menu, maybe having memorized how to activate those menu items with keyboard accelerators, etc. These people don't need Getting Started guides being shoved in their face! To these people, a Ribbon is just a second index to some random subset of the features they use, that takes longer to navigate than the primary index they're already familiar with; and which, unlike the primary index, isn't organized into categories in a way that's common/systematic among other apps for the OS (and so doesn't respond to expected top-level-menu keyboard accelerators, etc, etc.)

I think apps like Photoshop have since figured out what people really want here: a UI layout ("workspace") selector, offering different UI layouts for new users ("Basic" layout) vs. experienced users ("Full" layout); and even different UI layouts for users with different high-level use-cases such that they have a known set of applicable user-stories. A Ribbon is perfect for the "Basic" layout; but in a "Full" layout, it can probably go away.

This is it. Ultimately the best interfaces are designed for experts, not beginners. "Usability" at some point became confused with "approachability", probably because like in so many other areas, growth was prioritized over retention. It's OK if complex software is hard to use at first if that enables advanced users to work better.

Really, the most efficient interfaces are the old-style pure text mode mainframe forms, where a power user can tab through fields faster than a 3270-style terminal emulator can render them.
