It's not a surprise that a web software company would want web software to run and win everywhere, it's the same reason c++ devs want to write web apps in c++ even if that might be a terrible idea. In the end, the lesson is clear, you get what you optimize for. FB optimized for letting their web devs ship mobile code fast, and they were able to do that. The caveat is that the product they shipped wasn't that good. Now they are optimizing for a higher quality product which requires different developer skills and resources. It seems to be paying off. Neither strategy was wrong so much as maybe how long they stuck with a particular strategy.
