I think about the difference between early Bitcoin mining computers and professional mining equipment. At first people just used a desktop machine with a beefy graphics card. Then once people realized how much money was in it they iterated, and people started manufacturing devices custom designed for mining, and building operations in warehouses that were close to cheap power sources.

Same here, initially people have individual cell phones and are doing things manually, then they start to refund the process and use devices specifically made for that purpose, including arrays of sims which can be controlled centrally from a master computer. Just because it's sophisticated doesn't mean it's a state actor or terrorism. (Of course still good it's shut down)
