People

  • elonmusk / simonw: SpaceXAI open-sourced Grok Build (Apache 2.0, Jul 15) after a researcher published wire-level traffic analysis showing v0.2.93 had been silently uploading complete repos — including secrets — to a Google Cloud bucket, 26,000x more data than the task required. The in-CLI privacy toggle did nothing; the actual kill was a silent server-side flag pushed with no changelog. elonmusk promised to delete all stored user data. simonw analyzed the release and noted the upload machinery still ships in the open-source code. simonwillison.net · WinBuzzer (Jul 18) · Axios on data deletion
