Quite. However, with GPL software, I don't have to worry about the
copyright holder claiming patent infringment against me for patents used
by the software as distributed by him. If my patent grants under the
proposed Apache license are terminated, I do.

Please see my full rationale in

I'm not following you. An author of a derivative work can certainly add
exceptions to the GPL, just like they often do to allow linking to
OpenSSL. However, that doesn't make the OpenSSL license GPL-compatible.
