I am not trying to construct anything. I just described what happens and what I expect. "where you have the ability to elevate your own rights to somebody else's repo's contents." This is not an accurate description. There are two repositories: the original repository, and the fork. Nowhere I want to to elevate my rights regarding the fork to the original repository. " Name a computer system that intentionally allows people to do that." If somebody sends me a word document per Email, I can edit it without someone else being able to delete the modified word document.
