Right, it would be one thing if there was evidence that OpenAI asked the actress to imitate Johansson. But people are saying that using this voice actress at all without Johansson's permission shouldn't be legal, which is a bizarre claim. If someone thinks my voice sounds similar to a celebrities, now that celebrity owns my voice? In any other situation, everyone here would think such a standard would be completely outrageous.
(For what it's worth, I didn't find the Sky voice to sound anything like Scarlett Johannson personally)
