If I am performing an edit to use 'superior' wording, then it's to nuance the meaning, not change it -- otherwise my entire credibility is at risk... which is entirely my point. If I say "Ramadan begins at sundown" and then later say "Ramadan begins at sundown at Mecca", then that's an example of a change for superior wording. It likewise still has comparable meaning. That's the kind of context involved here. But go through the links cited above in the original article. That's clearly not what's happening here. For a religion that prides itself on accuracy, this is a farce.
I'll tell you exactly what the Muslims would do with this, though: the existence of these redacted passages allow them to quote really nice sounding words and say "we are a religion of peace" while knowing that they have no standing whatsoever. You see, there's another principle of Islam also at work here: you can lie through your teeth about what Islam teaches if it would advance the cause.
