You just made this up and spun your own narrative. Meek Mill was not signed to Roc Nation as a label. They were strictly his management. Meek his whole career has been under Atlantic and MMG. And Meek's $11 million comment was strictly music revenue. It didn't include and show money or endorsements.Meg doesn't realize that she basically jump out of the frying pan into the fire. Jay could've brought her out of her contract and didn't.
Meek Mill admitted that he made 11 million in 10 years in a similar partnership with Roc Nation.
I can't think of anyone outside of Rhianna who really got paid fukking with the Roc but since Jay takes a hands off approach and has Desiree run day to day shyt people don't blame him directly when they get jerked.
Jay really never co signed her other than that one Beyonce feature he hasn't jumped on tracks with her like that. Jigga had a co album with Jay Electronica but nothing with Meg. Basically Jay is just collecting from her.
J.Cole is Roc Nation and I'm sure he's made plenty of money
