I read the article through computer translation, so I may have missed some subtleties.

That said, I agree with those that don't find an issue with this player's actions or attitude (as much of the attitude as I could discern). It's a competitive environment where people are playing to win. When their opponent breaks the rules, their opponent should get a penalty.

If anything, I would actually be happy if more competitive players did this - i.e. call judges for every single warning-eligible infraction. Why? Players who cheat at competitive are able to get away with it because other players let it slide. If a higher proportion of competitive players called us on every mistake their opponents made, cheaters would either get caught out, or start playing honestly.
