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.
You keep trying to claim that a different person's private repo that you have forked has somehow given you ownership over the contained information. That's just not the case. Forking their code doesn't make it yours.
