The reason why Signal is not an open protocol like email has been argumented by Signal creator Moxie before (can't find the article please help). It has pros (evolution is faster and thus it's easier to compete with proprietary solutions) and cons (single point of failure) and Signal devs are well aware of that. We should stop acting like Matrix and Signal are competing with each other. I happily use Matrix but my grandma will not, ever, not in this world. And my mother has a hard time figuring out what a browser is. If we want everyone to be somewhat protected, adoption cost must be lowest.
