It occurs to me that instead of removing the field (which I'm sure people who used Company credits cards are looking for) they could simply have made it clear that it was the user's billing address they were looking for, instead of the bank's.

It might have resulted in more revenue if they had done it my way, since there may be people on business trips that now think they can't use a company credit card.

Or not. That's the thing with dealing with the public... Without paying really close attention to what's really happening and people are saying, you are just guessing.
