As far as I can tell the damage is because metal shields that were covering the chips have been removed so that we can see what they are. These shields aren't intended to be removed and aren't relevant to repairability.
They had to take a metal shield off to see this chip, not surprising if that caused some damage.
The linked details suggest that the Marvel chip supports Bluetooth 4, but PS4 specs only say 2.1. Possible for Sony to update this in a later software update?
