I just don't find them equivalent. Medvedev played, played his best or not, and lost, but he played the tournament. Not a hardship, just a hard loss to bear. And look at all the other hardships you cite in terms of Meddie, Berrettini, Cilic: injury, covid, and being Russian. In terms of all of those, who had control over his own destiny? Only Novak, and in terms of playing the AO. If you're injured, you're injured, if you're sick you're sick. If you're Russian, according to Wimbledon, you're out. Only Djokovic had control of his own destiny, and he chose hubris.
