Of course most cases short of a severe hardware defect can be unbricked given the knowledge, time and means, that's not the question. I'm referring to the rising tendency on YT and social networks to call any software crash, DoS or whatnot a "brick" when it can be mitigated by simple user-level measures such as a reboot, or in this case, by turning off BT.
IMO the term should be reserved for firmware faults or the levels below. Wikipedia gives a pretty good definition: https://en.m.wikipedia.org/wiki/Brick_(electronics)
