I have a hard time swallowing this. It sounds like a classic case of confirmation bias. "We did these nine things and were successful, therefore these nine things made us successful."
There's no data which tells us which of the nine building blocks mattered, if any, and to what extent.
What's more likely is that they believed these nine things were important -- and some of them quite possibly were -- and their belief has been confirmed by their success. But that doesn't mean if you duplicate these 9 features you will be successful, or that you have to duplicate all 9 in order to be successful.

All-in-all not a very helpful article.
