As others have commented, this is not a Framework product. That's part of the beauty: they open source there designs, allowing for third parties to easily make things like this (and much more beside). I believe at some point someone in the community was trying to design one of those slim ethernet ports that expands open when you need it (the jack doesn't really fit). Apparently some of the mechanisms for doing so are still proprietary though.
