There are two rights associated.
 Rights to Usage
 Rights to Modify

When you take a piece of code licensed under GPL and "modify" it, you
are required to make your changes available and also under the same
license ie. GPL. So the rights to modify comes with covenants in GPL.
In the case of BSD and ASL, there is no such covenant.

It may also be pertinent to know that under any license, the recipient
cannot change the copyright ownership or the notice for eg. " ... The
Regents of the University of California.  All rights reserved. ..."
