"It reminded me of when, in 2007, Drew Houston stormed onto the scene with his "GDrive killer," which was, of course, Dropbox."

So wait, Drew Houston specifically made and positioned his product in response to perceived competition, and the moral of the blog post is "Focus on your product instead of looking over your shoulder at the competition." Does not follow. The moral I got out of it was that perceived stiff competition can drive you to make something really, really good, even if the competition never actually materializes.
