It's a special bit, that's it.
More likely it's a whole set of bits. Why do you think they're doing this? Apple invented a new screw. Why do you think they did that? None of it is intended to slow down professional repair businesses, it's to stop DIYers.
You might as well complain about locking lug nuts as a whole because that's really all this is.
LOL locking lugnuts prevent theft. Do you think that's what the purpose of this is?
