“commonly known as the Chinese Communist Party (CCP)”
For an example, there are many similarly charged terms "commonly used" to identify geographic areas surrounding Israel, but in modern discourse we use "Occupied Palestinian Territory" since 1999.
North Korea remains North Korea. CCP remains CCP. Blackwater remains Blackwater, not Akademi or Xe or whatever bloody thing they're called now. I'm not going to just go along with whatever rebranding their PR agency told them to do.
