Who said she ran a script to exfiltrate a bunch of emails related to Gebru? The Google statements I saw weren't so specific. She allegedly copied the documents a month ago. The simplest explanation of why they aren't public is she didn't want them to be. I don't think it's useful to speculate about her motives when we don't even know what she did specifically.
