There are some big advantages of decentralisation in communication. Data is one - with a decentralised solution you retain ownership of your data. The other is who controls the platform... With a centralised service, one company owns the users, and can do pretty much anything they like to extract value from their users and their information. They can harvest data, they can advertise, they can share their users’ data with other companies... With an open, decentralised service, what the service does is out in the open so all parties have to act fairly
