@sharlatan @elduvelle @drahardja I spent years in law school and personal study on top of that to learn about copyright law. It cannot be explained on social media. But, fundamentally, in the US, something must be an expression of *human* creativity to be copyrightable. The tools may be whatever, but at its core it must be human expression.
And transformation has nothing to do with that. The term transformation is from the fair use doctrine, and has been perverted by anti-copyright folk.
