The title of the article uses the word "colluding".  I don't think this lawsuit has merit if the basis is collusion.  The schools aren't working together to admit students of wealthy families in the hopes of future donations.  They're all doing it to some extent but they aren't working in collusion with other institutions. 

FWIW the article states;
Stanford and Princeton universities are among the wealthiest colleges not listed as members on the group’s website.

I think they are being sued for coordinating their efforts and essentially agreeing to not compete financially for students. 

it reads to me that they are being accused of fixing the price to bring in a bright but under-funded student.
