This seems like a significant distortion to me. Neutrality can mean that people who provide infrastructure and services may provide them to everyone without being considered to endorse particular uses or users. That doesn't mean that either the infrastructure or service providers or the advocates of neutrality literally believe or assert that "nobody is actually wrong".

From another angle, neutrality can mean that no one, or no entity of a certain type, should have or should exercise certain powers of judgement or discrimination. This also does not mean that nobody is wrong.

This is true across all sorts of situation in which many different entities refrain or are urged to refrain from making particular kinds of judgements or interventions, and there are lots of potentially powerful reasons for such restraint—quite a lot of them having to do with Schelling points that different people can (eagerly or grudgingly) agree on to stop conflicts or disagreements from escalating or infecting everything.
