I tend towards thinking that that's acceptable behaviour, though I don't
have a very strong explanation as to why I think that. People obviously
feel that this level of patent termination is fairly important - it's
pretty common in current licenses.

I think this is more difficult. The OSD doesn't require that a license
give you a patent grant in the first place (BSD is an obvious example of
one that doesn't do anything related to patents). Effectively,
terminating a patent license just turns the license into one that didn't
grant you a patent in the first place. If that license would be OSD
compliant, I don't see any real way to argue that that sort of clause is
