HP Tuners said it’s not just a chip issue that causes bricking. You have circuit board material, the wires itself, voltage regulations in the entire vehicle system, etc. I could careless about bricking because I have a pic a part here that has all the PCMs I need to replace. However other people in the country doesn’t have the luxury of a endless supply like I do.

There are plenty of “circuitry” issues with GM trucks. The NBS cluster is a good example. While resoldering is a common fix, there are other issues dealing with circuit board runs, circuit board components, chips, incorrect input voltages, etc. The cluster does nowhere near the many things the PCM does. Plus the constant heat cycle of the PCM from being in the engine bay for NBS trucks makes them susceptible to electronic problems. That why PCMs can be bricked and a simple chip replacement won’t fix it.
