On most a bunch of Bitstream fonts the copyright says this, or similar:
“Copyright 1990 as an unpublished work by Bitstream Inc. All rights reserved. Confidential.”
My question is this: What the heck?
It's obviously published. I have it, so it must be published. Not only that, but this exact statement is the copyright embedded into the [[Bitstream Charter]] that was given to the TEX community with an open license. (The [[Bitstream Vera]] copyright and license is much more specific.)
Is this their way of trying to control copyright indefinitely, since under American law the creator owns absolute and indefinite rights over any unpublished works? If so, they need to look up the definition of "published".
