Per the ID based tech chart here (http://discoverygc.com/forums/showthread.php?tid=107926) it would appear that it is a 10% core for the liner with a freelancer ID. I'm assuming that the liner falls under Bretonian Civilian Heavy.
As for why, that would involve looking at the minds and motivations of the admin/dev teams, which is a scary scary place filled with spiders, snakes, and centipedes. Therefore I won't go there.
