The AFL also expressly provides for different terms, and other licenses with sublicense rights are often interpreted to permit it as well.  (Larry actually had a little to say about the usefulness of this in a paper on topic from way back when at http://rosenlaw.com/OSL3.0-explained.htm, at the very end.)  A sublicensor can offer different terms of their own to someone they grant a license to, provided that they include the original UPL notice, such that even if they offer a license under different, more restrictive terms (whether commercial or FOSS), the user is always notified of the original offering under the UPL from the original authors as well.  So in reality, they can just go fetch the original source code and go from there if it started out as an open source project under the UPL, just like they would under MIT or BSD.  And in any event, the ability to sublicense, including on other terms, is not unique to the UPL.

 Regards,
