OpenAI seems to be silently re-enabling model training on Codex chats

My company is pretty paranoid about leaking IP to the frontier labs through prompts, so we've all been diligent about disabling data sharing in Codex/Claude Code/etc. But yesterday my coworkers and I noticed that the setting had been silently reenabled in Codex. None of us knowingly opted back in.You can check your settings here: https://chatgpt.com/settings/data-controls. Look for "Improve the model for everyone".Curious if this is an isolated issue or something more widespread.EDIT: looks like this has been noted before https://news.ycombinator.com/item?id=49643556EDIT: apparently you can also turn off data sharing here: https://privacy.openai.com/policies?modal=take-control
