I contacted them. Response is below in itals. Apparently I'm some sort of guinea pig, but rest assured, it's being used to "improve" the overall member experience. Some improvement.

We would like to inform you that in the Bing Rewards program, we test and learn, making regular updates and refinements. We constantly make changes to the program which may include changing the number of credits that can be used to redeem a reward. As a part of our testing and learning, credit requirements may sometimes be different to other users. This helps us improve our overall program and the member experience.

We apologize again for any disappointment our recent changes may have caused. Thank you for being a loyal Bing Rewards member and be sure to frequently check your dashboard to take advantage of offers to earn additional credits.

Thank you for your kind understanding.
