> Gnome 2 was as far from Windows as any GUI that I've ever used
How very bizarre. It is _extremely_ Windows-like, with a trivial rearrangement to make it slightly less obvious. Basically, the same functional elements have been split up and separated to make it less obvious, that's all.
* The Start menu has been split into 3: Apps, Places, System.

* The single integrated taskbar has been split into 2, with a lot of wasted space.
* The top panel holds the 3 parts of the Start menu, then the equivalent of the Win98 Quick Launch bar, still on the left as in the original; and the rest is the system tray, now bigger but still growing in from the right.
* The bottom panel holds the app-switcher buttons, flanked on the left and right by some trivial new features: a show desktop button on the left (which Vista aped on the right), a virtual desktop switcher on the right (which Windows 10 finally gained, but only on a keystroke so it didn't panic the horses), and the trashcan (because the GNOME team seem to hate desktop icons for some reason).
The functionality is identical but spread out a little.
You've never used anything less like Windows 9x? Oh, my, you can't have got out in the world much, then.
Here is a quick list of things radically less like Win9x:
* Lisa OS: multitasking and file-based, but doesn't have apps or programs as core abstractions; you tear "stationary" off "template pads" to make new files and the invisible apps handle their own types of template. Global menu bar at the top, which Windows and GNOME never had.
* Classic MacOS. Much simplified from the Lisa for a 128kB machine with no fixed disk. Replaces the Lisa's template system with simple "programs" and "documents" to save disk and memory space. No visual buttons for apps or windows; no app launcher other than the file manager; critical functions right on the desktop, such as drive icons and trashcan.
This was protected by patents: that is why Win95 had to put the drive icons in a folder.
Later gained abstractions for networking, symbolic links, and multitasking, but some felt bolted-on. E.g. the Apple menu for sysadmin stuff became user-customisable and you could make it into a Start menu analog, but the OS didn't do that by default.
* DR GEM: a copy of classic MacOS, but menus are drop-down not pull-down.
* Amiga Intuition, AROS, MorphOS: again a Mac rip-off, but the menu bar is hidden until you right-click a new top status bar. Clunky but avoids a lawsuit. Folders do not show all contents unless specifically requested; files must be assigned icons by the developers. Drives have device names, a little like VMS, which is better than just meaningless letters but not as helpful as MacOS volume names -- but that's an option.
* RISC OS: no menu bars; the first taskbar-like panel ever, which radically holds drive icons; an app folder, an early ancestor of the Start Menu but sadly not global, just for apps bundled in the ROM; window button controls to send to the back of the Z order; dialog boxes constrain mouse movement so you must choose an option; no file open or file save navigation, so you must drag to the filer to save; intelligent use of 3 mouse buttons, so there are only context menus, but the right mouse button _adjusts_ instead of simply acting -- meaning no need for a scroll wheel.
* OS/2 2 WPS: folder based, but folders are virtual abstractions and not part of the filesystem, which is mostly hidden. Driven by a template system much like the Lisa, but poorly supported by 3rd party vendors. Uses different mouse buttons for dragging, selecting options etc. Preference settings is direct so there are no "OK" and "Apply" buttons: click something and it happens immediately. Uses tabs very widely, much more so than Windows 9x in the early days, but intelligently (if not prettily) they are vertical and colour-coded. Differentiates windowed from full-screen command prompts, whereas Windows let you toggle, later removed from Vista due to the introduction of a compositor. Linux never offered the choice.
* EPOC 16: keyboard-only GUI with file management integrated into the program launcher.
* EPOC 32: touchscreen GUI but most apps run full-screen all the time so there's no window management; keyboard summoned menus; app launcher integrated into status bar and silkscreened onto the display bezel.
* Sun OpenLook, Irix, CDE, etc: a chaos of experimentation and ideas but multiple quite usable GUIs;
* Sun Looking Glass: a true 3D UI -- flip windows over and there are settings on the back; no need to minimize when you can stack windows on their sides to put them out of the way, but still read the titles like book spines.

That's without going into stuff that's more exotic, like Smalltalk or Symbolics Genera, which have GUIs but they are for programmers not users, so they expose the code and the IPC of the OS directly rather than end-user-level metaphors like "file icons".
Take a proper broad look at the whole field, outside of the PC world, and GNOME 1 and 2 are obvious blatant Win9x clones, just with a very minor rearrangement.
I absolutely refute your assertion, I hope persuasively.
