Lets say this in another point of view to the hacker or w/e "You only have rights over something you did yourself, if your datapack includes a single file that you didn't made, then you don't own it and it can be posted" So the owner got more rights than the "hacker/stealer or w/e". Because he/she did something atleast didnt he/she?, The hacker does not have ANY right at all does he/she? It sounds logical, The owner maybe did atleast 1 file of 100 files that means 1% rights about the datapack while the hacker didnt do anything = 0% rights. I dont know what you think but this seems logical... ;o
Even if all the scripts and ect. was made by other ppls than the owner, the owner did the job to make something out of it.
Example: We say some guys own some LEGO parts, they give it to a guy for free and he builds a good thing out of this parts, Does the thief(hacker) have the right to give that thing he build out for free?
This may sound stupid...
