Disk Warrior hasn't been updated for at least 2 years and, as I understand it, Apple's file system is so stable that DW is unnecessary (at least Apple will think so). As to Microsoft, the only Office app that I use is Word because, oddly enough, I find it to be fairly intuitive and trouble-free compared to Pages, Libre Office, and some others that I have tried. I downloaded and installed Bean and Growly Write (and they look interesting) but I haven't used them. At any rate, MS Word does what I want so I bite the bullet and pay the fee. Life is too short to quibble.
