Then install another piece of software rather than the Gnome-branded software.
In Linux, I can eat my cake and have it too if I really want to -- I can run Amarok but use Gnome if I want. If someone wants to spend their time developing a browser suited exactly to the philosophy of the Gnome desktop, it's your decision whether or not you want to (un)install it. The only thing that gets wasted is their time.
Most non Gnome-branded apps work fine in Gnome. If GNOME wants to duplicate existing software, it's Gnome's right to do so. It's also your right to install what you want.
In other words, go to your favorite package manager, and pick what you desire. Don't be upset that you have more options. Options are the beauty of open source.
