I have spent the past couple days thinking...and speculating.
This is my speculative conclusion (one of them...lol...I have overlapping theories),
The WTS was court ordered to shut down extraneous building projects. The shutdown is too sweeping to be a headquarter planned move. It appears to be an anticipated move but not a voluntary one.
As stupid as we would like to think that the "powers who be" are in the Tower, I don't think that it is as simple as "they ran out of money". I think it is quite possible that the WTS has been forced, through court action of some kind, to stop the outflow of money into wasteful building projects.
I believe that time will tell, but it won't surprise me if this was a forced shutdown. A forced shutdown that the WTS knew was coming.
