My best guess as to the 'real' reason for going to monthly Awake?
FINANCIAL!
In recent years they have made 2 significant changes in the magazine distribution process.
1- The end of mailed-subscriptions
2- Reducing Awake to monthly
In addition, recent years have seen a notable decline in the number of heavy books released. More brochures, ect. But less of the bound books. And the books have moved to perfect-bound style instead of the case-bound variety of previous years. All cost reducing efforts.
The change of subscriptions took the cost out of the hands of Brooklyn and into the hands of the individual to get these magazines distributed. The elimination of one issue of Awake per month represents a virtual 25% reduction in the cost of publishing magazines. Probably even more than that, since with this change will come the inevitable reduction of staff at the printing facilities. Even though this is 'volunteer' labor, there is still cost involved in housing, medical, ect to keep these boys at Bethel.
I think we see the financial wheels starting to squeek a little bit here.
Just my opinion
