I don't see what's surprising -- companies that earn money selling product can make even more money by cutting costs. And if OSS software gives them an equivalent (or even better) solution, why wouldn't they use it? For any sizable production deployment, the cost of nginx licenses could be applied to hire a number of engineers to help maintain the OSS software. I don't know what their volume licensing is like, but at $2500/server list price, costs add up quickly.
