Secret Service dismantles telecom threat capable of crippling cell service in NY

The whole "crippling cell service" thing ... it doesn't seem like it was the plan or intent based on what they found. Seemed like just a setup for scam calls and someone decided to make some threats (maybe a customer of theirs) and then they got caught.
from the news report I could believe it's both a state actor, and primarily designed for fraud, but I do also believe there's an attack risk in simultaneous cell flooding. How much that magnifies into a real risk I don't know. Sports venues routinely call in mobile microcell vans in S.E.Asia (I've seen them in Taipei) to backfill when 10,000+ people want to ring mum from one location. So there's some capacity-risk issue with simultaneous use.
I also think that basic heat-maps of L2 signal strength and seen IMSI would have been a very strong clue something was up. If you put the city overlay into a GIS and heatmap the cell towers and binding states, you'd be going "hmm for a 10 household building, with 1000 simultaneous cell connects.. WCGW"
What if e.g. flooding the 5G/4G state forced people on roaming profiles to use weaker protections in a 2G space?
I feel like if the intent is to do that thing you wait for your moment and do it.
Rather I think it’s just a scam site that was careless and maybe rented some time to someone who made some threats.
