IS IT BECAUSE THEY REGION HATIN?

WTF is up with FAB replacing Wayne with Young Jeezy for his new single: Diamonds on my chain.
Wayne was supposed to be on there and I think it would have been better. Fab said in a recent interview that
the switch was due to "label difficulties". Damn that we all know that was region hating at its finest.
Now we all know fab is signed to Dej Jam. Now could it be because Jay said, Young Jeezy would be a better fit for the single instead of Lil Wayne? or is it just plain Ol' region hating? What you think?
