I could not possibly care less. I choose software based on what works (insofar as it is a tool, and that is the foremost metric by which it is just judged), and part of working involves being compatible with the rest of the documents I handle, the vast majority of which are not produced by me (or my software choices.)

If you want to compete with Word, make it righteous and compatible, and I will purchase a copy immediately.

However, given the choice between the moral high ground or a text editor that does what I need it to do (including compatibility), I will choose the latter every last time.
