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, …?
Facebook takes record of every of your activities on their platform, although it’s a way for them to know what you’re interested in and be able to place targeted ads. But if you ask me, I would say that every social platform or online platforms are the same, and you should mind what information you’re giving to them. Any platform can get hacked and hackers can steal your information and use it against you. So limit the information you’re giving.
