Read carefully! It says, "Information". This is NOT the project results, it is the originally provided material. I always keep a CD ROM of the project itself, and provide one to the customer as well.
There's a big difference between SPECIFICATIONS, which are mutually developed to create a project, and original proprietary information.
Of course. In actual practice I rarely see such a §6 anymore.
I have occasional military projects where you only get paper copies, serialized, dated and signed-for, that must be returned.
