"if you are developing a system management tool for Ubuntu, acceptable project titles would be "System Management for Ubuntu" or "Ubuntu Based Systems Management". We would strongly discourage, and likely would consider to be problematic, a name such as UbuntuMan, Ubuntu Management, ManBuntu, etc."
Ждем запрета называть программы k* без причастности к KDE.
