@indigo Perhaps, you're right when it comes to internet and biggies like Google, Facebook etc. But do you know, it doesn't end there. Anything and everything we do using our plastic cards, Online trans-actions etc, will always help anyone to track us, if anyone wish to.
To be fair, some companies will do that for the sake of customer and with good intention of serving and meeting customers' emotional needs by trying to understand the 'life style' of customers by tapping to customer data.
