Here's Hilton's answer, it's in corporate speak, and pretty much what one would expect:

Hello Mr. Jailer,

Thank you for your message to Hilton Reservations and Customer Care. It is my pleasure to assist you today with your concerns regarding the new redemption levels.

First, let me say that we can completely understand your level of frustration given the current economical environment that everyone is facing and apologize for the timing of this change. Moreover, let me assure you it was not our intent to raise point costs at this time in response to economic pressures as relative to the Hilton HHonors program.

Although Hilton HHonors has not raised reward costs since June 2003, we have been committed to offering various opportunities to earn even more points through the Points/Points earning style, as well as earning opportunities through our co-branded credit cards, car rental, and shopping/dining partners. As such and in order to continue to remain competitive, the decision was made to increase the cost of hotel rewards without taking away the earnings opportunities currently in place.

Hilton HHonors is committed to continuing to grow our program and benefits to all of our most loyal customers and in order to do so, we have to manage how the program is structured accordingly. We sincerely hope that you can understand our position regarding this change.

We appreciate you contacting us with your concerns and thank you for your continued loyalty!
