As a product owner who uses LaunchDarkly, my preference is to always abstract complexity if its not core to my product. I am always an advocate for tools and services that allow me to get to market quicker, while reducing long-term overhead. An internal service like LD would need to be built and also maintained. I think many people overestimate the complexity of services like this; it seems simple but execution is always more difficult (scale, bugs, features, etc). Cheers to LD for providing this service so my team can concentrate on our core.
