It is possible this opens things up a bit for set top boxes. Dunno.
But as far as decrypting/ripping/playing blue ray movies, that sort of
software has been available since even before the very first BD drives
even appeared, first used on HD-DVD disks.
Though I have never yet acquired a legal or illegal player for either
format. For some reason about that time I just sort of lost interest in
collecting movies. At first it was probably just the expense then I
just sort of never bothered. Or maybe it was just that my kids are
grown now.
