I'm usually pretty critical of self-promotion, but in this case they gave a real world example of how they did something related to the article's contents. They didn't even provide a link or an app name, just said that you could find it in their history if you were curious.
I think that's about the best you can do not to promote your product while trying to give real-world examples of things that are being discussed.
