I used to think this way. In fact, when applying for a job, I would only submit my resume in PDF. I've stopped this. I know you think you're doing good to the world by telling people to shove it, by adhering to your standards. But what you're really doing is exactly what you claim they are doing to you. The world works in Microsoft Office. 9 out of 10 computers have Microsoft Windows installed. Gartner has estimated that 9 out of 10 Microsoft Windows installations have some version of Microsoft Office installed. With the advent of online document, spreadsheet, and presentation software popularity, and the fact the Microsoft Office documents are natively supported, it's a losing battle. There are good strong technical arguments why proprietary formats should not be used, even including open binary formats. You won't win that argument. It doesn't help your cause either, when the reply back to your refusal to open a .docx is "Well then, install it, or don't read it." By you trying to force work on others, you will simply just be missing out on what the content of the document is. Unless, of course, you install LibreOffice/OpenOffice.org. If you want to send open standard document formats to your contacts, go for it. But by demanding that the sender do extra work curtailing to your needs, so you don't have to do extra work installing office software, is hypocritical. Get over yourself. No one cares.
