Of all the large companies that are now large internet players, do anyone particularly scare you in terms of how you data and track could be used? Amazon, Facebook, Twitter,
?
I think Facebook is the most evidently intrusive. They monitor all of your online activity pretty much and then shape your thoughts and such with targeted advertising. There will come a time in the future when the world decides it needs to take a step back from such intrusion in to their personal lives.
I believe too that Facebook is devil of all. They have been in the market since long time now and they are not doing great now a days. I mean they track us all the time with the caches, cookies etc and then alter the way we surf over the internet. The flashing ads they show are always relevant to what we daily surf what we watch and much more. Even if you dont have to shop then they will put big ads on your page and they will change your minds. Also I dont think that our photos are stored securely always. I mean there have been so many hacking reports in my country and the misuse of such photos continues always. Dont know but I now only use Facebook rarely.
