This seems to be the crux of the problem. I'm new to the OSI list (though
I've been part of other free software license discussions for quite some
time), so I'm not sure how much leeway is generally allowed to "open
source" software vs "free software". Please point out to me when I'm
incorrectly equating the two.

IMO, such an ability is absolutely required by open-source software. The
chinese dissident case (Imagine a group of people who want to modify and
share software among themselves, but who will be executed if it is
discovered that they are working on this) is one common way to phrase this
requirement.

This is the choice of such customers. They have source, so they have
control of thier systems. With luck, they're likely to ask you for help
(being the original author) if they decide something is wrong.

It needs teeth to protect the software recipients from the software
authors. Teeth that protect an author from the recipients are the
opposite of free.

Neither qualify as acceptible in my book. I'd be interested to hear
from OSI board members whether this is an area where "free" as commonly
used by the FSF and Debian differs from "open source" as used by OSI.
