Gnome as standard DE for Ubuntu instead of Unity

Gnome is a big step backward for Ubuntu, there are several usability flaws in the main user concept of Gnome in comparison with Unity.
Why is Gnome the new standard DE for Ubuntu? What is the problem in continuing Unity development and refinement?

- There is no real pixel-saving in Gnome (i.e. oversized window-titlebars, missing globalmenu support, no integration of the window-titelbar in the menu-panel, etc...)
- The app menus are not consistent, there are some menu-entries in the "main-menu"(in gnome panel) and some entries are in the "Hamburger" menu in the app window and for some apps, like evince, there is a second "Hamburger" menu (one with points, one with lines) for file-specific options. This can't be a feature, it is definitely a bug!
- The file manager Nautilus is a mess and nearly unusable since most of the options(!) are stripped from the settings! This can't be a feature but is definitely a bug! (remember: Linux is always the freedom of choice - even in the settings of an app. And why stripping existing and working options?)

i don't know the real reason why Marc abandoned Unity as the standard DE in Ubuntu but in my opinion it is the biggest mistake he ever made except abandoning the Ubuntu phone.

i know that this report will marked as "opinion" and no one ever hear the voices of the people that still see the real potential in Unity and the design flaws of Gnome!
And i know that i am not alone!

Perhaps there could be a way to reUnite the Gnome project with the strengths of the Unity project for the sake of a big and bright future for both as a synthesis!?
In my opinion Synthesis is the way of the new age, of the future, and everyone who works against each other will fall behind...
please remember the strengths of Unity and see that the great success of Ubuntu definetly has to do with Unity as the standard DE!
What Unity wants is UNIFY and what Gnome does is DISUNITE! (for examples see the bugs on top of this report!)
