Copy: obviously, I want them to store my data and move them from HD to HD. Distribute: This is what a distributed version control system is for. Perform: Yes, please, format my .md files as specified. Display: show me my code please. Store: already covered. Modify: this is dubious but if I upload a change, they need to modify it.

So I want to give them those rights if I want the service to work as desired, otherwise, it would not be bitbucket.
