I see it as trying to pander to the growing restlessness of the shrinking rank and file. They are lowering the bar for the commitment it takes to join or remain in the org. This is by no means the "Big News" of two years ago but I think it is significant. How would you feel if your employer told you he was reducing your work hours but your pay would stay the same?
This is consistent with my theory that the WTS is strategically becoming just another LDS, Adventist, Cristian Scientist, etc. sect that perks along indefinately. I think eventually the entire thing will be based on a heavenly hope and the burdensome Armegeddon/New World doctrine will be faded.
