Bro, you have a right to your feelings but to be fair, you have to put it all in context. They were well into their beef before any blackballing took place. By all accounts, 50 started this beef and for no real reason. According to 50, he was at a video shoot with the guy that had robbed Ja previously. He got mad when Ja wouldn't speak to him. So much so that 50 claimed he left the video and decided to come back to do something to Ja, but an "OG who was holding them down" (I'm assuming Preme) stopped him before he could do anything. That's when 50 started dissing and taking shots relentlessly.
Before things spiraled all the way out of control, reputables from both sides organized a meeting with Ja and 50 to squash the beef. What did 50 do at the meeting? Snuffed Ja and took his chain and rapped about it.
You're framing this as Irv being a bully who was just blocking a nice guy from being able to make music when it wasn't that simple.
