Privacy Laws. In some countries (eg the whole EU) privacy laws about data are VERY strict and I don't think you can force them with just a license. To make an example here you must identify in a sort-of-contract who are the people who manage (in any way) the data, for which explicit purpose and for how much time. Also you have to give a way to delete it in a permanent way. And typically you cannot share that data with third parties not explicitly know at the moment in which you write the contract and the user accept it (you can't be vague, they must be people with name/surname/etc or companies). So consider that, in most cases, your program cannot be used if there is even a single data relatable to privacy laws that it gathers (and again, here in EU even temporary geolocation is considered covered by privacy).
