We're really happy to work with the WireGuard. We communicated with Jason throughout the process and have a ton of respect for him and the entire WireGuard community. In the short term, we need the flexibility to quickly update our code base to support the project we built it for. That's harder when you need to coordinate with people outside Cloudflare and when we need to move as fast as we plan to. However, we really believe in open source and want the WireGuard community to thrive. We licensed the code very openly (3-clause BSD) and WireGuard may choose to fork it. If they do, we'll support it and plan to contribute any improvements in our own fork back. Over the long term, we're very open to merging this back into the upstream project.
