From Wikipedia:
"Ubuntu (/ubntu/ oo-buun-too; Zulu/Xhosa pronunciation: [ùúntú]) is a Nguni Bantu term (literally, "human-ness"") roughly translating to "human kindness"; in Southern Africa (South Africa and Zimbabwe), it has come to be used as a term for a kind of humanist philosophy, ethic or ideology, also known as Ubuntuism or Hunhuism (the latter after the corresponding Shona term) propagated in the Africanization (transition to majority rule) process of these countries during the 1980s and 1990s."
As such, Canonical itself is on shaky ground as this could be construed as violating clause "C) Terms that Disparage, Falsely Suggest a Connection with, or Bring a Person, Institution, Belief or National Symbol into Contempt or Disrepute" of USPTO regulations.
