Any reason why they claim to be something else ? You say they "found another host" but this doesn't look like an official freeciv property.

Maybe it's them but the presentation is weird. I'm not sure if the license allows you to re-release as another name, it probably does, but then presenting it as "they found another host" sounds kind of disingenuous.
