Claude and Codex users hit reverse-engineering blocks OpenAI calls accidental
First merged summary.
Users of Claude and Codex report reverse-engineering blocks and bans; OpenAI says the Codex limits are accidental and being fixed.
People using Anthropic’s Claude and Claude Code and OpenAI’s Codex to reverse engineer devices they own report safety checks, warnings, and account limits. Reported uses include unbricking abandoned IoT devices and replacing smart-TV software. An X user said OpenAI banned an account after Codex was used on Samsung TVs, citing cyber abuse. The reverse-engineering project Decomp.wtf has shut down. OpenAI engineer Tarun Gogineni said there is no Codex prohibition on reverse engineering, that the blocks are mostly accidental, and that difficult decision boundaries are being fixed. Practitioners quoted by 404 Media say they are moving toward local and open-weight models.
