Unfortunately, WT is not transparent with financial information never mind other data. It's not like other corporations which publish and offer a yearly (and quarterly) audited financial reports to the public.
Cut backs and branch closures in themselves do not prove much. WT has adopted the new way of distributing information in the 21st century, as has been adopted by numerous other organizations
Why print, bind, warehouse and ship paper when the same information can be distributed inexpensively to their target audience, virtually any where in the world through a digital pipeline. Of course, since so many people were utilized in the production and distribution of paper literature, those people and numerous additional support staff are no longer needed.
With digital, the printing costs are transferred to the target audience (JWs) since their audience who want to read that information, then need a computer, tablet or other device. If any of the target audience want a hard copy, they need to arrange printing to paper at their own expense.
WT currently have little new information to offer, unlike when F Franz was their 'oracle'. WT find themselves presenting the same, over and over again so they may as well present once and use that info for a longer time period, all while claiming 'simplification', growth and speeding up of the warning work.
Since most JWs with devices won't bother printing and keeping paper, changes to doctrine are easily performed to the online master document, which will immediately update info utilized by the majority of JWs.
