Emacs has handled CTRL-C even in text mode since its inception. That was

Killing Emacs from within its window requires CTRL-X CTRL-C.
Emacs is it's own world. I don't think it is reasonable to compare
its command set to anything else.
Fair enough. Try CTRL-C in a Firefox window and see that nothing
happens. If you want to kill Firefox started from a terminal window,
CTRL-C in the terminal window is needed (or you can apply the usual exit
methods--click on the window bar, use the menu, or use a keyboard
shortcut). To kill Firefox started from the menu, there is nothing you
can do with CTRL-C. An unresponsive Firefox must be killed with xkill or
the GNOME app-killer.
(c) Often it seems as though the decisions about what keys to use for what
purposes (and many other UI design decisions) are made by the developers
with no attention paid to context, history, or relevant standards and
guidelines.
Except that many of the decisions predate the history and context
you expect them to follow. Most of what we expect these days
is at least slightly related to IBM's CDE work and motif
circa 1989 but motif's licensing kept it from being used
in the early open source work. I don't think MS Windows
follows it strictly either.
Also a fair point, but the problems crop up often enough with new software
as well. I commend the GNOME folks for trying to standardize the behavior
of GNOME apps, though I occasionally think they carry the idea too far.
(It seems they can't win, though. If they push standards too hard, folks
bitch about lack of flexibility. If they don't push hard enough, we get
threads like this one. It's a delicate balance, and we will know they've
achieved it when nobody is entirely happy.)
