Just to clarify this: proof of concept in this case means proof that a cyber security issue can actually be exploited to hurt the target software/hardware.

People in the cultural left in Europe often use this term in order to sensitively describe people who are (historically) discriminated because of their phenotypes. (E.g. Asians, latino, blacks, etc...)

I know you are satirical, but you are also kinda correct. Non-POCs would typically be "whites" (at least in Europe) who are still privileged, going back (at least) since colonialism. (E.g. Nordic, alpine or mediterranean phenotypes")

Not passive aggressive at all, your comment, also i totally didnt know that it doesnt mean Person oft color in this context
