exactly, we are wondering if a software could stay free (copylefted) as
a program (GPL), as input data (copylefted) as output data (copylefted)

so that all the users are obliged to share their input/outputs back to
the community

I am aware that probably it's not possible to regulate in this manner
input/outputs, but we are wondering, only discussing to have clear
ideas.

thanks a lot! :)
