They're still configuring the software that generates the music, aren't they? If a musician chooses a chord progression (for example) and then hands it off to an algorithm (maybe one they designed), isn't that enough to count as composition? In all of these cases, there is a lot of human thought and choice involved, it just doesn't happen to look like it does when someone plays an acoustic instrument or writes a score.

Edit: I should say, I do think that a lot of electronic music should be considered craft rather than art. But not all of it.
