At least they are up-front about their motives.
I just got one of those fine-print "Change of Terms" notices from Chase. At the very end under "Other Notices" it clearly states:
"The principal factor we considered in amending your account is maintaining profitability on your account.";-)
Among the reasons they can choose to close my account is "account inactivity".
I guess the name of the game is not how responsibly you use credit anymore. It's more a matter of how much profit they can make on you. They make the most money when you take cash advances; and even more if you then make a late payment. Since I don't do that, I'm not a very profitable customer, so they'd rather not have me as a customer at all.
In the end, they end up with a lot of high-profit customers ... but maybe also a lot of high-risk customers. They make a nice profit until the house of cards collapses. Is there something about this "business plan" that sounds famililar?
