Search Engine Optimization means optimizing for search engines means if your metadescription on Google sucks and your sublinks are nonexistent, you have bad SEO.
That's part of SEO. But if you're optimizing for search engines, that includes controlling how your result shows up and what extra things show up too.
If you want to stick to your pedantic definition, then I'll put it like this: Apple isn't just at #1, they have an additional eight links present before anything else shows up. Droid has one link to their nine.
