There are other areas like this, too. I'm part of a firm that does grant writing for nonprofits, public agencies, and some research-based businesses (http://www.seliger.com for the curious). Word and Excel are standard, especially for any documents that may touch governments. All narratives are written in Word and budgets in Excel.

I like and approve of LibreOffice but it doesn't seamlessly transfer complex styles or tracked changes to and from Word. When an organization is working with people who bill in the hundreds of dollars per hour and a grant in the hundreds of thousands or millions of dollars, cost of MS Office is a non-issue. I approve of and generally support OSS (I'm writing this in Firefox), but the level of integration into the MSO world is ill-understood.

I've also written novels and the whole publishing industry and infrastructure is based around Word.
