Removing labels off of contribution boxes is probably done for legal reasons, because if money is being giving by way of a contribution box with a label for such and such and the WT corporation takes it and uses it for something else or just pockets it could be considered fraud.
I'm thinking this new arrangement now allows the WT to do what ever they want with the money. They are getting ready to start liquidating assets and rob the rank and file of all that they can get.
