What does that have to do with anything? AIUI they have compiled their own distro (which is not Ubuntu). It leaves the rest of us with the problem of how (or even if) we support this chip. Do we offer two versions of Fedora, with twice the storage, twice the build time, and toolchain changes to support these two architectures? Or do we compile Fedora without RVC, impacting performance on chips which do support RVC? This is an unfortunate (but long-predicted) side-effect of not making RVC mandatory for Unix-like RISC-V systems.
If you are referring to that screenshot in the article, that is just the PC it's connected to. If you look closer at the terminal you can see it's running Buildroot.
