I could be totally wrong but back when this was posted in Jan, I had a strange interaction (pretty sure it was one of the q team) on voat about:
NO OTHER VEHICLE TO REGAIN ENTRY
who was patiently explaining that this refers to the (NSA) data collection needing to be re-collected under different pretext to be usable for court admissible evidence, (parallel construction).
so I'm guessing that ALL VEHICLES OF DELIVERY REMOVED means that other (CIA) agency's access to electronic surveillance has been cut off. Also would explain why they are coming here to find out whats going on.
