No, it makes no sense to change a well-known phrase to an unfamiliar and goofy sounding one just to appease a silly ideology that injects racism into everything.
Black box vs clear/open box are very well known terms. Some people use the term opaque box instead because it a more clear antonym to clear/open box.
Nonsense. This is all part of the "oppressive language" concept peddled by the neo-Marxist authoritarian types.

This is the first time in my life that I head the term "opaque box" used instead of "black box" in this context. I couldn't even find this phrase using a Google search.
