Great comment. While Blue Ocean Strategy does away with competition for positioning several battles remain, most notably:

- The battle for talent - The battle for capital - The battle for partnerships - The battle for distribution, etc

In the context of the article I also make the argument of startups being at war with the government and even customer that are hesitant to adopt new technologies. Take the case of Uber for example. Class act Blue Ocean against the status quo albeit at war against governments, similar rising companies, etc.
