Yes I got the data to cancel the premium subscription. So I was authorized by the owner of the account. But it was already to late, because he wasnt able to reach me in time. There are reasons which I am not allowed to mention here.
Also I know the owner of the account IRL. I would trust him with my accounts as well.
Also it was out of question if that is permitted by TOS or not. Many people use common accounts for all kinds of stuff. Like bots for some buisness.
I dont see this to be worth a discussion.
