Impact JS - only for money?

Seems to be incredible that a great framework to do HTML5 games will be sell for 99$.. too much for a little market with no way (for now) to try something on coding site :(

As said here :

"You couldn't consider releasing a free license for non-commercial development?"

A non commercial license with good opensource option (even with dual license system) could be a good point to build a big community of HTML videogame programmers, an occasion lost I think.. so: think twice!
