Greg, those retroactive later-version licenses don't work the way
you're saying.

Once you've released code under a particular license, no one can take
those terms away. However, you can give people the *option* of using
your code under a different license, or not (that's the "this version
X, or any later version" clause).

Thus, people will always have whatever rights you originally released
the code under -- CollabNet cannot change that later. However, you'd
be explicitly granting them the right to *choose*, later on, to use
some other terms. Since our current license already permits
proprietary forks, this can't result in anything too awful. But it
does give CollabNet the ability to retroactively rerelease things
under even more liberal terms in the future.

The scenarios you describe below don't happen:

But that's not what happens, because you still always have the option
of choosing the earlier (original) terms. In fact, you (the user) get
to select whichever version of the license you like the most, from all
the versions since the earliest, inclusive.

Same rebuttal.

Same.

Not scary if you realize all the options available to every user.
