Creating learning material isn't something that hinges entirely on trustworthyness. Sure authors of learning materials may be biased towards certain practices or styles, but it's trivial to verify that the content itself is legitimate - any coding tutorial that says 1 byte chars can increment up as far as 4 byte ints is going to get called out quickly. But for a referee putting down high scores from a video game, the referee's value stems entirely from the idea that the referee is a trustworthy observer.
