Clause 5 of this license is not a 4-clause-BSD-style advertising
clause. It is an acknowledgement requirement which seems comparable to
ones I've seen in some other licenses generally regarded as free
software/open source (though probably raising issues of GPL

The indemnity clause is rather broad; while two licenses with upstream
indemnification requirements, Apache 2.0 and Eclipse Public License
1.0 (plus its ancestors), are OSI-approved, those clauses are narrower
than this one. I myself don't think licenses with blanket
indemnification clauses should be accepted as Open Source without
further study, or some consensus among other organizations/projects
involved in license gatekeeping (e.g. FSF, Debian, Fedora) that they
present no problem.
