I'm porting Orespawn and have a question

I know the original creator tried to sue someone but not why and was wonding if I'll be able to share the ported mod with my friends or if this is a mod that only I can use without potentially getting in legal trouble?

I've already ported more than half of the mod to forge 1.20.1 and I am using the 99% of the original textures aside from the ores that I had to change to fit deepslate level and also I added other mod api support such as Tinker's Construct and Lucky block integration while keeping the orespawn mod standalone without any dependencies.
