The summary says this specifically with respect to hard drives, which actually makes some sense, especially in the age of SSDs.
I don't know how many articles I've read here on the subject of recycling computers and the number of commenters who have said the only way to do it is to take the platters out and drive a nail through them and such.
Would you not expect Apple to do the same?
SSDs are even trickier because you can't do something like the secure wipe procedures where you overwrite with 1s and then 0s repeatedly. When SSDs exhaust their write cycles they mark the particular segment as no longer usable and leave them as they are. However, the data stays, so if you can bypass the drive controller I presume you could still read the data.
