Anonymous Coward writes "GitHub's Atom, a new text editor blending C++ and web technologies, is now being released as a limited beta. The new editor, which claims to have partial TextMate support, is extensible with the help of a centralized add-on manger (the same way Eclipse does) and is heavily integrated with the github platform. The final licence is not known at the moment, but the project already makes use of over 80 open source software packages.
Access to the beta is currently "invite only"."

So while Atom is going to be highly customizable and extensible, it does not sound forkable.
Personally, I'm just too dependent on familiarity with my main editor to go off and switch to a non-open replacement. It would need to have some key feature which I absolutely could not live without, that could not be replicated in an open editor.
