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.
