Which law schools take a cut of summer associate salaries?

Not sure if "taking a cut" is exactly how the policy works. I've heard having a BL summer associate salary will affect how you receive need-based aid, or that the salary is not fully yours.
I heard this a while back about Harvard and then again on social media a couple weeks ago about Harvard, YLS, and Stanford. I don't really know the specifics.

Does anyone know which law schools do this and how it works?
