@aproposIt's actually even more retarded than not wanting to do it in house, most would opt to have that sort of access to your info to resell it.
The reason they don't is that when the breech inevitably happens they'll be accused of not using "industry standards" and their insurance won't pay out and leave the company on the hook to pay damages. This is true even if the security in place was better.
They would rather centralize everything and make one big target and ensure that everyone is fucked when the inevitable happens.

Much safer to occasionally fuck up catastrophically while being able to say it's some other guy's fault!
