He didn't cut them out of the profits, it was solely his thing. They've all said it since it was created. Rae's beef later on with Wu-Wear was that since they all had to put up money for when he went to see investors, when they were no longer as profitable as artists, he felt he should get a cut of the Wu-Wear. But he also said Power did cut him out of other things they had together.
But Power has been sick for a while. You can look at him and tell. He also got very active on IG the past 2-3 years, posting old pictures, memories, reminiscing captions and all...I think that was one of the reasons for the Final Chamber tour now. It was their last go round around the world, with everyone living present. But they probably didn't say anything since he never officially said something.
