Calling Gluon the "Java counterpart to Xamarin" is a bit of a stretch. They are a fraction of the size of Codename One which itself is a fraction of the size of Xamarin. Since they are clearly so tiny any claim to trademark might be problematic. Furthermore, the domain is different. They can't assert computers as a domain (gluon gun from Quake if I remember correctly). It is used as a sort of umbrella name for a lot of different products they have but none of them is a programming language.
