@vulonkaaz Piracy is theft and murder with the help of a boat - I believe you are referring to prohibited copying.

A program that you don't have the source code to is useless, as you can't feasibly make non-trivial changes to it, in a reasonable amount of time, even if you decide to risk it and modify it illegally.

Redistributing leaked or exfiltrated source code is of incredible risk, as you risk prison time.

minecraft was Java, so decompiling it does net roughly similar source code, although it is not the same and does not contain any comments, so such is a poor substitute for real source code.

Yes, minetest mods that infringe copyright will not be accepted, as the minetest developers do not want to have to deal with copyright trolls.


Free software developers need to make sure to keep the copyright and licenses in order, so people can legally contribute improvements with confidence that they're not going to end up sued.
