Apple also claims that after Liu learned he was under investigation, he directed OpenAI colleague Yu-Ting Peng in June to destroy evidence, and that Peng agreed to do so. The filing additionally alleges that Liu used a tool at OpenAI that shares a name with an internal Apple engineering application. "The MacBook represents the very limited information Defendants provided so far (and only after weeks of delay), and shows Apple is not conducting 'fishing expeditions' but that its trade secrets are being used and evidence is being destroyed," the filing states.
