I am not asking how. I am asking the binary Yes/No question of whether Apple’s FairPlay DRM copy-protection as used on their iBooks ebook content is known to have been cracked/broken/breached, citing evidence.
According to this CNET article in 2012, that version of FairPlay was breached. Rumors suggest Apple enhanced FairPlay. I am simply asking for a definitive answer as to the current situation of 2016.
