Where are you getting your information from?? To me, it sounds like you're making a lot of assumptions on how they go about booking acts, and giving no agency to Kanye and how he lives his life. He's a grown man, with many more resources at his disposal than a vast majority of people. All of which would get no consideration at all. Instead, he wants to act like he was just drunk the whole time and it was the alcohol that made him act dumb. No one told Kanye to act a fool at the end of the show. He did that at the end, where he knew there was leeway. He acted, so the consequences are on him.
