@ij@metin Matrix *is* decentralized. I run my own Matrix server for the family. My employer runs a Matrix server. Several universities run their own server. And we all can send each other messages without any difficulty.
@jze@metin I tend too disagree. Yes you can run your own server. I do myself. But the matrix.org server is too big and vector.im too. So Matrix as a company has a central position and will get notice of nearly all relationships and Communication. That‘s centralistic.
