Clearly they want to move as much as possible from being a literature based religion to being a new digital/video religion. They would end all printing tomorrow if they could.
The problem is their doctrine requires all JWs to be 'witnesses', ie, they must publicly witness to Jehovah. And they believe they are scripturally required to do this door to door.
So they are currently in a limbo...they preach video messages door to door. Dumb dumb dumb.
They are trapped again by their own out of date quirky doctrines by being chained to the door to door work belief. Its just another stoopid old belief that needs dustbinning, along with so many other weird, eccentric fringe beliefs of the borg (generation, 1914, birthdays, blood, etc etc).
Solution: shed 'new light' on the door to door work, making it no longer compulsory for all in the congregation to do it. Make it something for pioneers only, bit like how the Mormons do with their 19 year old missionary 'elders'. The rest of the congregation can just do informal witnessing, phone witnessing, or giving tracts away in the street or in malls directing people to JW.org to watch videos there instead of on some schmucks tablet on a doorstep.
