You are suggesting that it is coincidence that they contacted SJ to provide her voice, they hired a voice actor that sounds like her, they contacted SJ again prior to launch, and then they chose that specific voice from their library of voices and tweeted the name of the movie that SJs voice is in as a part of the promo?
I haven't suggested what they have done is illegal, given that the fictional company that created the AI "her" is unlikely to be suing them, but it is CLEARLY what their intent was.
