You are not "gingerlime" who said that, I understand the original as "moral/social obligation" and not "legal obligation" but you seem to be putting the word "legal" on the users' mouth by saying what they "actually" mean?

As a Spaniard living in Japan, what social rules should I use to apply my social courtesy on Github?

I am gingerlime. I simply meant obligation as MUST and social norms / courtesy as SHOULD. So I guess technically you’re correct that it’s not a legal obligation, but I think the GP’s point is valid.
