Oh, that's what you thought of! I was confused as why people take offence at Rocky.
As a Calgarian, the first thing I thought of was Rocky Mountains. Due to their proximity, you see the name is so many things and places here. For example, the area surrounding Calgary is called Rocky View County.
Ubuntu is a Nguni Bantu term meaning "humanity". It is often translated as "I am because we are", or "humanity towards others", or in Zulu "umuntu ngumuntu ngabantu" or in Xhosa, "umntu ngumntu ngabantu" but is often used in a more philosophical sense to mean "the belief in a universal bond of sharing that connects all humanity"
When they replied, what I originally had written was "Why is it bad branding?". I thought it would be obvious from the parent comment that I was talking about Ubuntu, but I think they thought I was talking about "Rocky Linux".
