Yup it's a strawman argument. And furthermore, even the rhetoric used to downplay the idea of holding companies accountable is off:
The idea of "blame" (with some handwaving) carries weight in court and sways juries. And companies are getting sued for big sums over negligence regarding SIM-swaps, like here https://www.techmeme.com/190723/p15#a190723p15
You cant control a sim swap attack.
