Well actually it does have to do with basketball. The flopping and crying/whining about fouls has absolutely benefitted him "on the court" over the years, with soooooooooooooo many questionable/borderline calls going his/his team's way...
MJ also benefitted from flopping and whining for fouls and favorable whistles. If you think otherwise, you never saw him play. There is actually video of Magic and Bird (who benefitted from favorable whistles themselves) giving him shit about it by saying "don't get too close to him or it's a foul".
No one has said Lebron's big mouth isn't part of why he gets so much flak. But his big mouth has nothing to do with his on-court accomplishments...yet you MJ deep throaters sure like to pretend it does.
