Perhaps "should", but they don't.

Compared to most other licences? I'm not sure about that. It's more
complex than most BSD-like and Apache-style licences, which are a
significant proportion of "other".

Indeed, so it looks like the Affero -> GPLv3 upgrade route is dead,
since the original Affero doesn't mention the possibility of relicensing
to the GNU Affero GPL.
