I'm a vegetarian, but *certainly not* because meat tastes bad. There are many people who share a similar view.
Since this is /., an analogy might be an open source enthusiast who uses OpenOffice/Abiword/GNOME Office/KDE's Words/etc. -- why not just use Microsoft Word, given that (to some extent) the open source solutions are just clones? If the only reason you don't use Word is because you don't like Word, then...well, yeah, you should probably stick to vim or emacs. But if the reason you don't use Word is something else (doesn't run on your platform, has some [perceived moral or financial] cost associated with it, etc.), then a clone is a pretty good choice.
