When and why to deprecate filesystems

There's a different between "not wanting to be associated" with someone and not being able to ask them for help with technical stuff. You can get acquaintance with code without Reiser, even if it's harder. Besides, I don't need to give you a reason to start using reiserfs because I don't think anyone should, it might have been pretty advanced at the time, but its glory years have passed. That doesn't change the fact that "oooohhhh its author is a murderer we shouldn't use/maintain it" is a piss poor argument.
