What do you think about the DQ of Kato/Sutjiadi in womens doubles?

They are going to fine Michael Ymer for smashing the umpire’s chair after the most disrespectful refusal to go see the mark up close in his match against newcomer Fils. Can you blame a player for venting feeling humiliated and mistreated on a very crucial point in the match? In any case Rogerio Santos the umpire should be fined twice as much as Ymer..
