Surely "only for humans" is the obvious default given that there were no AI megacorps when these licenses were written?

Surely it's always been obvious that the person doing the sharing is the one to decide on the terms of the sharing? Maybe I want to share my cake with you but not with someone I don't like? How is that not my decision to make?

I'm absolutely fine with people having different sharing philosophies. Different licenses with different nuances are a thing. But I don't like this take that everything that was shared is automatically retconned to be included in AI training data. That's not the spirit in which I shared my stuff. Maybe that's the spirit in which you shared yours, and I respect that.
