Peevish Question: Word Attachments

I get tons of all-campus email, and more and more of these seem to be of the form “Please see the attached Word file, containing a plain text document with minimal formatting that could just as easily have been pasted into the body of the message.” Happily, I have my campus email forwarded to my GMail account, and I can opt to view the text as HTML, rather than opening Word to see it, but it’s irritating.

Is there some reason why it would be preferable to send campus announcements out as Word files rather than as plain text in an email? Or is this just a case of laziness and technical incompetence?

Is there a polite way to tell people (many of whom outrank me) to knock this off because it irritates me to no end?
