That's not the point.
If an article's title is altered from it's original design, it makes it impossible to do a search for that article, which will result in multiple postings of the same article with simply a different title.
Imagine for a moment if everybody here decided to change the original title of any given article to one that they thought was more salacious, humorous, graphic or whatever....
....the majority of your time would be spent opening up cleverly titled articles that have the same content within.
