What if you owned your Facebook account? And what if you found out that Facebook was analyzing your account and used that information to manipulate you through ads. What if a competitor offered to give you a similar experience to Facebook without the manipulation? You would keep all of your friends, all of your posts, all of you IMs. Your entire history would be intact. You would just access it on a different site. Hive makes this possible.
It gives power to the users for the first time. When you make an account on a given platform, that platform owns the account. With hive, you are the owner.
