I work for one of the organizations cited in the article and worked on this investigation. There were several arrests in 2016 and things have mostly been back to normal. You're right about jamming. I'm aware of several thefts in which covert cargo tracking or driver cell phone tracking was employed. At the end of the day they jam the signal, search the trailer, and discard the device or in the case of driver tracking..just turn it off. Tracking isn't the way. There is very little the shippers can do to prevent it as well. It's up to the shipment broker to vet and identify identity theft of the trucking carrier when the load is being booked. Very few of them have any sort of security practices. The industry is woefully susceptible to even basic social engineering attacks.
