Matrix being a known, agreed-upon protocol means that it is a potentially viable “mindshare locale” , while the transmission of which being entirely distributed and self-hostable.
People can simply follow @<username>:<server> handles just like @<twitterhandle> following as it currently works.
So all it requires to create the functionality is to add a dedicated “Matrix Feed” room to each user profile by default. The user mindshare will gradually come as people seek greener pastures of uncensorable platform, while moderation is entirely self-policed by individual communities curating their own list of persona non grata.
What considerations have I missed that could possibly stop Matrix.org from picking up what seems like a low-hanging fruit?
