If you're in college or above 18, I expect you to understand that Beyonce is a human being, not a deity. Human laws applies to her as well. If I'm already made and I keep giving you my most powerful works and you keep taking them for granted, I'll give them to an artist who appreciates them. Simple as ABC. Tedder definitely expected/wanted XO to smash, he gushed about it so much.
It's not all bad though as younger and fresher producers won't boycott her because it's an honor. BOOTS for example, is not out for the $$$.
