I think that dude Professor Skye had the best breakdown of Drake being upset... called it "transactional" friendships... Drake doesn't really have those friends that Kendrick has and can speak on like he did on The Heart pt. 6... so he forms these friendships with people that he can mutually benefit from... gave the example of Drake calling Adin Ross BROTHER dozens of times, and then saying in order for them to stream again they'd have to get paid "billions"... essentially, anyone he can mutually gain from, in one way or another, is his brother.
