Huh? Email >>>>> Twitter over like 40 years or more? You don't work as an engineer, right? If you would, you would know how low the quality of most centralized technology is that is created by big corps. Most of the good stuff is decentralized. But the problem is that decentralization also means that the edge has more responsibility. And that responsibility is what people don't want to have. So they rather use a centralized bad system, because it's "easier" and then every few years they can blame all their own laziness on the centralized service provider and even read about it in the news.

If you need another example google a tool called "git". It is used by almost all software developers nowadays and even by quite a few authors. You don't need to setup anything to use it. If you have ssh you can just share your text based data with others by giving them access to your repository's directory. I bet it transfers more MB/day than Twitter. But nobody counts it because it's so distributed that it's hard to put an owner label on it. (Although the originators can be named quite clearly.)
