I worked at Unity on Build Automation/Cloud Build for nearly a decade. Let me assure you, that tech debt is NOT being fixed any year soon. It’s due to a fundamental disconnect between executive leadership wanting to run the company like Adobe (explicitly) and every engineer wanting to work like a large scale open source project (Kubernetes, Linux, and Apache are pretty close in style). The only way anything gets built is as a Skunkworks project and you can only do so much without funding and executive support.
