Poem or integrity check?

Recently, Apple confirmed that it had included a poem in its Intel based machines as a message to hackers of its operating systems.

Your karma check for today: There once was a user that whined
his existing OS was so blind he'd do better to pirate
an OS that ran great but found his hardware declined.
Please don't steal Mac OS! Really, that's way uncool.

Looks like they have copywrited this too!

Anyway, this looks like a clever trick and I have not seen this before. This poem for which they have not even tried to rhyme, being unique, when looked at by the hacker would definitely be made public by the hacker. And if this piece of poem was embedded deep enough the kernel that would have been seen only by the successful of the hackers, the public knowledge of which gives a very high accuracy signalling the cracking of OSX.

A clever one!
