Seems pretty obvious to me.

Terminating a previously offered license and offering an alternate license
is exactly what I mean by changing license; I don't think there's any
effective difference, except that "changing licenses" is quicker to say.

I *am* glad to read that they believe that this is their right only under
the CWI license; I'm not sure I follow their logic, and I hope they don't
reinvent their logic for their new, improved license.

Yeah, that's true -- I was silly to not mention that.  That's a good
reason.

Anytime.  ;-)

Sorry about the alarm.  I just have been through a lot getting Python in
some use at my workplace, and I'm thinking how much HARDER it would have
been to do that after this license fight.

Maybe if we all *sound* really confident about this license not changing
*this* time, perhaps nobody will notice the change.  (I'm not doing very
well at sounding confident.)

<0.9 +/- 0.1 wink>.  Thankfully, my boss was clever enough to notice the
obvious Perl-risk.  I don't know what I would have done if he hadn't -- I
would have probably done those projects in Perl :-).  I've had to do worse
ones in Perl (ugh) while at school.

My boss doesn't want to find a basis for assigning probabilities to fears;
that costs money.  He'd rather preserve clearly defined areas of
uncertainty and doubt -- by which I mean he'd rather pick a license which
had never been challenged and was used by a lot of people.

A for reading the license -- I have.  I also read the previous license,
and it didn't lead me to expect the Spanish Inquisi^W^W^Wany license
change.  I hope that the current license lacks all vulnerability.  I hope
that no one associated with Python makes any kind of similar decisions; I
hope that CNRI is the only 'person' qualified to make that kind of change.

I wish they hadn't.

The interesting thing about my brand of paranoia is that I don't mind the
new license; I'm concerned by the FSF's dislike of it (but not seriously
concerned); my big worry is the question of how they got to do this, and
whether they're going to do it again.

It's mildly reassuring to see them claim that they won't do it again.
Very mildly, since I have next to no reason to believe them.

The only things that kept me quiet for so long is:

 - we have good people working on the problem
 - even in the worst case, I personally can ignore the problem and keep
   using Python.

There, I feel much better.  Whew.
