I think u'v just spoken really well. I believe that whatever can be used for the good of the public can as well be used to our detriment . The data collected by these social platforms you mentioned can be used for a lot of stuff including crime fighting and all but at the same time can be used to track down innocent civilian and we that, we are at their mercy but the truth is that we can actually do less about this because most people can't do without these social platforms .
