SBF is going to get the shaft, just like many other prominent white collar criminals, like Bernie Madoff, have. The reason Ellison is getting off lightly is because she made a deal with prosecutors and gave them all they needed to build a strong case. Same happens when people in a non-white-collar criminal organisation snitch, they tend to get decent deals. The reason a low level drug dealer doesn't get that is because he has no information of value to the prosecution that he can use as leverage.
