Traditional enterprise companies are agglomerations of IT systems from a sprawling network of acquisitions, subsidiaries, and partners. They collect fad languages, architectures, and proprietary ecosystems from across decades of computing history. And then try to somehow make them all play with each other.

At least in our world we have the source code to all the services. They have explicit and intentional APIs. They're constructed from a small set of frameworks and speak an even smaller number of protocols. Our enterprise brothers have none of that. Screen scraping, retrofitting TCP/IP stacks onto things that never had them, patching binaries whose source is long gone, etc.
