I have a suspicion that this is more about avoiding a big anti-trust quagmire. When they starting dabbling around in the Travel sector, they did get push back...but that's an area where the power is spread across a large number of players, none of which is a powerhouse litigator or lobbyist.

For insurance, credit cards, mortgages, etc, they would be at odds with a relatively small number of deep pocketed, litigious players with experience in political lobbying.
