Apple has a lot of power, but I doubt you can find any examples where Apple wielded this power to go after Hackintosh owners. Did they even go after iOS jailbreakers?
PCs running OS X don't get intentionally disabled, sites offering how to make your own Hackintosh don't get letters from Apple, the LA police doesn't raid your house.
They're even pretty cool with their OS media. No install keys, no limit to the machines you can install it on and upgrade version are really full versions.
