Maybe massive connectivity loss was the purpose. While something interesting was offline, maybe with security infrastructure disabled or weakened, likely at many places across the area, something interesting could have been done.
Hard not to jump to the conclusion that it was some Q-Anon inspired attack on "5G".
I don’t think Qanon conspiracy theorists are capable of tying their own shoelaces, let alone knowing how to pick a good telecoms target, choosing an appropriate explosive and quantity, assembling a bomb, planning timing and logistics of the actual bombing, and completing it without getting caught by the FBI or stopped by local authorities with minimal collateral. Nothing about this says “dumbfuck theorist”. I’m just an armchair detective though. I’ll wait for the Netflix special (complete with composite characters and fake events).
You don't have to be an idiot to be a batshit crazy conspiracy theorist.
