Bitcoin has a decentralized ledger where all transactions are stored. How would that ledger look for a decentralized Youtube or Facebook? Or am I missing something? Does decentralization mean something different in this regard?
I don't see these famous platforms decide to be decentralized. Decentralization entails a lot of things and on top of that is the control and censorship. Facebook and YouTube will never be multi-billion companies if they are not controlled platforms though they are open to the public still decisions on many matters are done by the corporate personalities and not by the users themselves. There had been many attempts to introduce decentralized social media platforms but up to now not one is flourishing all of them are still unknown and many are already dead.
