As for why it's bad, it's because they set down the precedent of wanting specifically Scarlett Johansen's voice, got declined, doubled down, got declined again, and then went ahead and did it anyway. They can say in their own defense that it's some other voice actress that sounds similar, ok, so produce that name, tell us who she is.
Absent that, it's Johansen's voice, clipped from movies and interviews and shows and whatever.
"Sky’s voice is not an imitation of Scarlett Johansson but belongs to a different professional actress using her own natural speaking voice."
