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".
