Do credit card companies dislike when you only use their cards for the extra rewards?
They don't like it as much as if you charge lower rewards transactions but they're not going to retaliate or anyting. Adverse action is taken based on your credit and the usual factors -- not on line items that you purchase or the MCC's of the merchants you shop at. If they're unhappy with how the rewards on their products are being used they'll change their rewards programs as they see fit.
