Competition law, they’re not allowed to share pricing information with competitors (being in an alliance doesn’t waive this, only a joint business). You don’t give them any permission to share revenue/spend data and it’s not part of IATA messaging data standards.
They have cleverly designed carve-outs for airlines that need different standards for different itineraries (e.g. AA, where it matters whether it’s in the JB or not).
