You still have no basis in claiming copyright protection hence you cannot set a license on that code.
Instead of the WTFPL you should just write a disclaimer that due to being machine generated and devoid of creating work, the work is not protected by copyright and free to be used without any license.
Has the world moved on from copyright? Or expecting other people to behave ethically and fairly?
No, and god I hope not.
But it's a real dick move to set up your CI the way you have. Zig explicitly requests using one of the many mirrors for CI instead of hammering the main ziglang.org site itself. Perhaps you've moved on from trying to be ethical?
For the copyright thing, I understand that there's legit ongoing debate around all this AI-assisted coding and copyrightability.
In this case of zpdf, while Claude Code did a lot of the heavy lifting on implementation, there was a real effort in architecture decisions, iterative prompting/refinement, debugging, testing, benchmarking.
My intent is zero restrictions: use it, fork it, sell it, whatever. WTFPL captures that spirit perfectly for me. It's as permissive as legally possible while being upfront about not caring.
The goal is just to make a useful tool freely available.
