By "stealing" you mean "paying the price Apple charges", right ?
Psystar is (or maybe is, since they first lost all invoices so they couldn't show Apple in discovery what they are paying, then when Apple got the court to tell Psystar that they _must_ deliver the information they went bankrupt, then when Apple got the court to tell Psystar that they _still_ must deliver the information even when they are bankrupt they suddenly don't find it convenient to be bankrupt anymore, in other words, nobody knows whether Psystar _has_ paid anything to Apple) paying the price that Apple charges to extra special customers who have already paid good money for Apple-labeled hardware, and who already have a previous version of the OS legally installed on their hardware.
Psystar is paying what Apple charges for MacOS X with a license that allows installation on a single Apple labeled computer. They are free to install every copy they paid for on a single Apple-labeled computer, and there is nothing that Apple could or would want to do to prevent that legally. They are not free to install MacOS X on their Psystar computers, and they haven't paid for that.
