“XEmacs at a crossroads”. 2017年7月27日閲覧。 “For the past decade, work on XEmacs has continued at a low level, and mostly not visible in user-level features. In the meantime, GNU Emacs has implemented almost all XEmacs features...At the same time, a number of features that XEmacs lacks, and would require substantial effort to port, have been implemented...the developers who have been the primary contributors of code currently have personal and professional commitments that prevent them from devoting enough time to XEmacs to implement the large features necessary for full compatibility with GNU Emacs for the foreseeable future...several developers who have contributed heavily in the past have acknowledged that they *won't* be doing so for the foreseeable future. It's only fair that we let you, our users and supporters, know about that.”

“Xemacs vs GNU Emacs”. 2017年7月27日閲覧。 “XEmacs is GNU software because it's a modified version of a GNU program. And it is GNU software because the FSF is the copyright holder for most of it... XEmacs has no choice, because much of its code is copyrighted by the Free Software Foundation, and is only available to XEmacs under the GPL.”
