Not all cryptocurrencies are scams, not all traffic on Tor is CSAM, and not matrix messages are spam. Some of us use all of these decentralized systems daily for their actual intended use cases of sovereignty and privacy.
Things like money and messaging are too important to a functioning society to allow any single party to control.
We need -actually- decentralized money and -actually- decentralized communication.
MobileCoin and Signal are neither and the results are predictable.
