I think the strategy has been more than fair, and I for one am thankful for it. We were given appropriate advance notice and had the chance to renew put the charges on a card with the furthest expiration date to maximize savings.
I think it is a case of not realizing the good fortune of this policy of being so fair, and therefore not appreciating it... and misdirecting the frustration of bad luck (lost/stolen card) toward a criticism of a more-than-fair policy. We humans are often quick to complain, but slow to thank/praise.
So, thanks Jon. Your policies are much appreciated.
