RMS was naïvely and foolishly applying the "no harm, no crime" principle. Once he was educated that adult-child sex invariably causes long-term psychological harm to the child, he changed his mind. He even called Epstein a serial rapist and was not shy about expressing his disgust for the man.

If you're wondering "How can a grown man not know that child sexual abuse causes harm?" well, this puts us back into awkward nerd territory: what you think is common sense may not be to a sufficiently awkward nerd.
