Would they like FB, Google, eBay, Apple et al to know which banks they hold accounts with, how often they access them, from PCs and from their phones? Or what religion you may follow? Or your other personal preferences? Would they like such organisations to put together a profile of what they think the person is like, based on the web sites they use, when they use them, what they buy from them and more? And then for those profiles to be used by credit rating organisations, or by employers during recruitment processes, or by customs officials when entering a country? All of the above without your explicit permission, perhaps because someone you know has thought it was ok, and with no verification that their assessment of you is correct?
