It's unfair to receive this type of treatment. Mac was disgusted with the crowd. It may be that they wanted an underdog to win, but unkind fan behavior often fuels Novak to excellence.
I can think of only one reason a crowd might show anger toward a player who is always respectful to his opponent, officials, and the audience. Like in Australia, much of the French population has been under pressure to submit to experimental vaccines, which has made them angry at those who show some individuality and courage not to surrender their beliefs. If not that, maybe they wanted the underdog to win which makes many of the fans just partisans.
