I strongly agree with you. The way things seems to me from lurking in
the agg mailing list is that Maxim has some clear motivation for the
license change.

1. Continue to allow general "free" access to AGG
2. Make those who intend make AGG "their own" product pay him a bit for
a different license

I think this is only fair. Antigrain Geometry 2.4 is as many have said,
a *great* gift to the community. And AGG >= 2.5 is "free" for the GPL
community. The fact that Maxim clearly don't want others to take all
profit for his great work is easy to understand.

I think his motivation is primarily to make a decent living from his
product. This will allow him to continue using his time on what he
clearly is talented and skilled at. In itself that is a very good
thing. If he is to change his mind about the licensing, as well as how
to contribute to the community, I think it is reasonable that those
that have ideas (proven by experience), or other means that can convince
him, come forward and bring their information to him. Now is the time.

It may be best to discuss this privately with Maxim, see contact
