If it's just function calls to the Wordpress code, I still can't see how it can be considered derivative. He also does not distribute Wordpress along with his theme. It's the user's job to put them together. This to me means it's separate and not derivative. This just exemplifies the viral nature of the GPL and why businesses need to seriously consider using any code that involves the license. This entire situation is a little hypocritical to me (for HN). Whenever there is an article about the piratebay (or piracy for that matter), there is usually a barrage of comments about how piracy is okay, it helps the content provider (because it's getting more usage), and it doesn't hurt or harm the original author. Now that it involves the GPL (a person defending their copyright/license ownership..just like the record and movie industries), the majority here are singing a different tune. This just means that it has nothing to do with what's right and wrong, but political ideology.
