ndee thanx for sharing the link.
Like I said, you are considering two dimensions at the same time. It’s not that you cannot do it, it’s just that these are different entities and should be considered differently. Once you’ve referenced that page, please consider the following stated in the beginning of said article:
“Games created in Blender (.blend files) are program output and therefore not covered by the GPL. You can consider them your property, and license or sell them freely.”
Thus, the content created by using some GPL code is YOUR property and you can license it at will.
As it is stated there, the executable is, technically speaking, code. Consequently, the same GPL freedoms apply as the ones hold for the code originally used to create it. This is meant to promote copy-left and disallow copy-right.
What you’re saying covers the technicalities of distributing a creation made with Blender. There’s a very subtle conceptual difference in there.
