The problem is, a lot of conspiracy thinking relies on people being publicly stupid and careless, then privately extremely cautious and careful. The Washington Post looks at what was happening internally when the voice was created, and finds that the casting call didn’t ask for anyone who sounds like Johansson, and the actress wasn’t told to sound like her or imitate anything from Her. People say, “That doesn’t mean anything, maybe they were just keeping their intent hidden!”
OK, but then they openly blast it all over Twitter? If you’re so open about what you’re trying to do with everyone in the world, yet you didn’t bother mentioning to the voice actress who’s supposedly going to implement this?
