OneEyedjoe hit the nail on the head! Back in the day they atleast tried to provide some kind of reasons or weird logic behind their ideas. Now, I think they realized that witnesses (and people in general) are very very distracted and are just eager to be told what to do, what to think and what to believe. They dont need Freddy Franz logic or Revelation like books anymore. Just point them in the direction and on they go.
This is western society in a nutshell. Technology and social media is turning people into drones. We went out to eat to a hibachi grill this weekend. Now mind you this is a show where the cook does all sorts of tricks in front of the table of 10+. Well it was amazing to see most glued to their phones and ignoring this poor cook.
This is society and the witnesses are not immune to it. The GB/ marketing or consulting company they hired knows this and is simply taking advantage. There is no better time to completely change the religion than now, while everyone is dumb and distracted!
No pesky details needed.
