I wrote before.
Datum was gathering your data from twitter and facebook etc.
Sphere is a social media also giving control of your data which you make using them.
You can't stop facebook and twitter selling your data with datum you can also sell it too but with sphere you can make your own decision.
What I dont understand is, what is the point of decentralizing a social network? I get that you will be in control of your own data, but why create a social platform?
People need social platforms. And the current ones are centralized also selling your data and no privacy at all.
So they are making a decentralized one which you can control your data.
If you don't need social platform i can get it but for the rest of the world, it can be something.
