This is politics - attempting to treat specific situations reasonably is the fast path to a kerfuffle. Note that if Phillips' campaign thinks this would have been good for him, it might easily be perceived bad for someone else. And that is an unstable equilibrium that easily leads to political escalations using OpenAI technology.

Clear lines on what shan't be done (lines drawn far away from the real grey areas) is a position that is both prudent and respectable by OpenAI.
