We must distinguish between "to a few" and "to a closed group". Since the
software is open-source, everyone has the right to distribute it further
with or without changes. Speaking of a "closed group" would imply that
the people that I distribute to would have no right to distribute outside
the group, which is abhorrent to the nature of Open Source.
What I was talking about, rather, was the opportunity to make a few
changes and pass along changes and changed version to my friends,
without being asked to make them available on a Web site too. Of course
my friends can send to other friends, and so on. Or they can post the
changed version (and the changes) on their own Web site, and so on.
Therefore, there is no discrimination; I am simply limited in my obligations
such that I only have to distribute the changes with the changed version, and
all is done.

Yes, you are correct. I simply wanted to point out that the fact that my
changes to a GPLed program are licensed for use by all does not mean that
I myself have an affirmative duty to make them available to all.

I think this is a good feature.

Yes, there are malicious people in the world, certainly.

Fair enough.
