copycenter: n.
[play on ‘copyright’ and ‘copyleft’]
1. The copyright notice carried by the various flavors of freeware
BSD. According to Kirk McKusick at BSDCon 1999: “The way it was
characterized politically, you had copyright, which is what the big
companies use to lock everything up; you had copyleft, which is free
software's way of making sure they can't lock it up; and then Berkeley had
what we called ‘copycenter’, which is ‘take it down to
the copy center and make as many copies as you want’”.
