Sorry man, i have no interest in engaging in this conversation with you. It's not my responsibility to convince you. I'm not performing any labor to find you sources. Please respect my license and go find an artist who's willing to work with you 🙏🏽
I'm not looking on being convinced or to convince nobody, I was just surprised when I discovered this reality and wanted to understand the reasoning behind it. No worries I did some Google myself and found couple of articles that have a lot of valid points, in any case thanks for your replies.
By the way right now I'm just learning but if I ever use your resources believe me, I would not break your rules, I respect people like you (and your work) a lot, I'm 20+ years developer and I'm an enthusiast of open source and communities like itch io.
