Because I've read more than just one article on the subject?  The point is 
to track down the key used to decrypt the content so the key can be added to 
the blacklists on future players.

The hardware players are required to have FLASH in them, because they need 
to update to new versions of blacklists. They're not (last I read) required 
to actually have a separate key per player.

It might. But it isn't.

Typically they often do, but contractually they may be forced to provide a 
separate key for each player if the blu-ray licensing folks feel it's 
appropriate given the structure of the decoder in the software.


Read up more on how it all works. It's really quite impressively complex.
