Also, to further put it in perspective, when Wilt scored 100, the day after it was a minor news blip. There simply wasn't the type of international, multibillion dollar interconnected across various industries entertainment goliath that there is today. The reason we talk about ref bias, specifically 'superstar treatment' today, is because it exists and because there is an actual incentive for it. We can debate the purity of the sport all day long, but at the end of the day, calls get changed to protect star players, calls get changed to protect close games, guys like Jodie Meeks will never ever get the same types of calls that guys like Kobe or Lebron get.
And yes, I think this is also directly related to how and why the NBA has gotten 'soft'. Before there was millions of eyes on it at all times who really cared if some elbows were thrown? who really cared if someone got pushed or tripped or whatever? You obviously had refs and regulation to keep it sporting but when you're not talking about billions of dollars running through and intense 24/7/365 media scrutiny, it's a lot easier to let things go overall.
