In theory, as long as disassembling is possible, anything can be cracked. It
just takes smart crackers (and perhaps more time) to counter the smart
anti-cracking techniques. If Fruit hasn't been cracked yet, it probably uses
some industrial strength program for software protection. Search any reversing
(which I hope is legal) forum and you're bound to find people posting for help
to illegally "unpack" executables.
