Recently I blogged about a press release that was issued in a Microsoft Word format.  Touching on a article I found on OpenSourceCatholic, I mentioned even the Vatican says Thou shalt not use proprietary formats.  The defense? 

Regarding your comment on needing $150 Microsoft Word to open the press release, you forget that ALL versions of Windows include "Wordpad," which opens Word documents. While we normally use PDFs, we used a document format so others (like you) would not have retype the information.

A little Microsoft-centric....
