They claim that what happened was very much not because they were 'carefully engineered and instructed to do those things'.
Similarly, some wikis which were hijacked by agent to be used as messageboard were actually not disclosed by OpenAI (probably trying to conceal, as website showed likely activity from OpenAI researchers visiting the site after the incident) and discovered independently.
I don't know how you can claim that this was still on purpose by OpenAI as some sort of publicity stunt.
