[License-review] Sublicensing

[Engel Nyst]

I'm not sure how to understand plainly 'sublicense' in an open license.
However UPL says more:

> permission is hereby granted, free of charge and under any and all
> copyright rights in this software [...] without restriction,
> including without limitation the rights to make, use, sell, offer
> for sale, import, export, have made, have sold, copy, create
> derivative works of (provided that this does not license additional
> patent claims beyond those covering the unmodified Software and
> Larger Works), display, perform, distribute, and sublicense the
> Software and the Larger Work(s) on either these or other terms.

Note "on either these or other terms". Let's say A develops software,
and licenses it under the UPL. A distributes it on their website, which
has the following Terms of Use:

> By using the services provided by this website, you agree you are not
> allowed to copy, modify and distribute the material made available on
> this website, including without limitation any documentation,
> software or data.

In my reading, these are 'other terms' which per UPL, cancel the rights
granted previously by UPL.

Am I allowed to copy, modify and distribute the software?

What if B distributes A's software on an identical site, does the
answer change?
