Here's an analogy: you write a blog post for a tech/UNIX audience, titled: "Why GNU tools are bloated" or something (stupid example). At some point, someone else posts a link to your blog post to a mathematics forum, changing the title to "Why Gnu Tools Are Bloated".
In those comments, people complain that they don't understand what kind of gnu you're talking about, that they thought you were talking about wildebeest herding, and they say you obviously should have expanded the GNU abbreviation in the title.

That's what I feel is going on here.
