It is, but to be clear I think the point there was not about public figures per se but about everyday people. Everyday (albeit obviously left-leaning) people would post the black squares out of a sense of obligation, and then the responses would be split between praising them for standing up for "black lives", versus half the people criticizing the poster of the black square for making a silly symbolic gesture. (I view it as the latter - a stupid symbolic gesture - BUT the context of the whole "silence is violence" meme is why these NPCs were in a double-bind: damned if you do, damned if you don't)
