I'm OK with uncensored anything for adults. In fact, I'd call myself "free speech absolutist". But I am not OK with uncensored content for little kids.
Obviously such decisions must be made on application, not model side.
Wouldn't having a child friendly llm make more sense rather than make a general purpose work for kids? Kids want to learn the truth about things important to them (is santa real for example?) but the truth needs to be framed for their ears. Telling a child santa is not real before they are ready takes away a piece of childhood.
