"People own and have control over all info they put into Facebook and “Download Your Information” enables people to take stuff with them" I don't find that very true. I don't think one has control unless one personally hosts the data. You have control over deleting your account and now control over downloading your data. This says nothing about how the ("the" not "your") data is to be used and what can be done with it outside your control.
