nope, we can do what we want with it, including charging for our work.
in the menus in anim8or, go "About > License...":
2. LICENSE:
You are granted a license to use Anim8or for personal, educational and commercial purposes. Anything that you make with it, you own. This includes images, models, animation projects, movies, etc. Of course if you use others work as part of your own you need their permission as well, but Anim8or imposes no restrictions on what you can do with your work. There is no fee for this license.

once again, a huge thank you to steve for being so generous with the awesome program he's written!
