Re: Is an upgrade to the Open Publication License possible?

changing the license.
Well, these are the problems with it:
(1) No explicit permission is given for modification, or for distribution of
modified versions. Sloppy, sloppy.

cited as possessive with respect to the title.
This needs to be removed (or substantially weakened) for it to be free. Well,
if it applies to modified versions, it does, anyway; it might be acceptable
for unmodified versions. For modified versions, it would be ridiculously

Unclear whether this means the person must *really* be identified (not OK) or
whether a pseudonym is acceptable (OK).

This is normally non-free, but might pass under the "patch clause" if the
"unmodified document" was located in the source package. It becomes deeply
obnoxious if derived works are *also* OPL-licensed, but since it's not a
copyleft, that can be avoided.

And, of course, the license "options" are non-free, but nobody uses them
