I know I'm late, but if you're curious, it does seem that one of the main contributors is a guy named SocDoneLeft, who is a American reformist socialist, that famously is also a little racist, so it's not really a surprise that he would use CCP instead of CPC. Always remember to check the sources, and the contributors for higly divisive things on Wikipedia. Especially considering that a third of Wikipedia is written by one guy, and he happens to be an anti-Communist border immigration agent with US security clearance. He is not the most unbiased guy in the world as you might imagine.

However I do get the confusion, since CCP is what the entire West calls it, but even if you disagree with them as a political organization, I still think just calling them what they're actually called, and not a thing seeped in a lot of bad stuff, is better. I do appreciate that you are willing to use CPC when you were corrected though, that shows that you are not stuck in your ways as many are with this, so thanks for that.
