Who cares who wrote it? Good code is good code, and Reiser is still often the best option for storing lots of small files.
I don't think it makes sense to change the name, but it's rude and vulgar to deliberately link to an old version of a page that makes fun of someone's murder.
You linked to an old version (from 2008!) of that wiki page that contains vandalism (a column labeled "Murders your wife"). Why?
Given your comment "no other file system has all the features of ReiserFS or Reiser4", I am guessing it is a crude and disgusting "joke".
diff between the page you linked and the current version: https://en.wikipedia.org/w/index.php?title=Comparison_of_fil...
"Murders Your Wife"

... How did that make it into Wikipedia? How has it not been removed!?
Edit: Oh, that's an old version. My mistake.

Looks like ZFS does? (especially now that it does have native encryption)
