You make it sound like rewriting MS Office is a bad thing. At its core, MS Office is a very solid piece of software, so why spend resources and divert focus to try to improve on something Microsoft has already made near-perfect? And rewriting it under the GPL license (so it's free) adds value to the project as well. Not to mention that by rewriting it, you make it easy for people to pick up your project easily.
