If they were really trying to get people to burn points, they would have changed the value of the points for a limited time, to say 2,000 points are worth EUR44. By keeping the same value per point, but allowing you to redeem as little as 1,000 at a time, is only going to appeal to a very small group of people, like those who have between 1,000 and 2,000 points in their account, stay at Accor properties very infrequently, and looking for a way to cash out. I don't see this having an impact on the behaviour of very many people.
