Nevertheless email stays the defacto standard for business communication and has stayed intercompatible with a wide range of clients, servers and plugins. So this graph could be better but is apparently not a big issue as long as companies and unis keep running their own servers, forcing big tech to stay with the standards.
That works when the decentralized protocol is the 800 lb gorilla first. You can’t get there with the fediverse in this internet era, sadly.
Email also doesn’t have a moderation factor that requires emotional work.
The matrix protocol is a good example to prove you wrong. It has been popularized in the past 5-6 years (i.e. this era of the internet) it has well over 100 million users and growing, is being used in hundreds of universities and wont stop growing, is being used by government bodies all over the world and has unified most of the software dev landscape into one protocol. Its hard fucking work and you have to start with exactly those groups which are easier to convince and then you can move on to the average consumer. Thats how email did it and thats how matrix will do it.
