Re: [email@example.com: Review of proposed Apache License, version 2.0]
I'm not cc'ing the apache license list, as I suspect tempers will stay
cooler if debian-legal reaches a consensus, then contacts Apache.

Thanks. I think the new S5 looks like this:
5. Reciprocity. If You institute patent litigation against any
entity (including a cross-claim or counterclaim in a lawsuit)
alleging that a Contribution and/or the Work, without
modification (other than modifications that are
Contribution(s)), constitutes direct or contributory patent
infringement, then any patent licenses granted to You under this
License for that Contribution or such Work shall terminate as of
the date such litigation is filed.
That's certainly better. It still has a problem in the following
1. I start using Apache.
2. I develop a new process -- let's say an encryption algorithm, like
RSA -- and patent it.
3. Somebody contributes an implementation of my algorithm to Apache.
This somebody has patents on critical parts of Apache.
Now I'm screwed: I can't sue Apache for illegally using my work
without my permission, or I'll lose my license to their code.
What this amounts to is a non-Free patent license, since it is
revocable by an unrelated lawsuit.
