I'm using Emacs to write the post.
WOW, that's really cool :-D and exactly my point when I say "great for a computer scientist, but not for the general non-technical public".

It's a great example of what my thoughts were when starting this thread:

I was under the impression (which could obviously be wrong!) that there are mainly tech and privacy enthusiasts at the Fediverse these days (Mastodon is a slight exception as it has become a sanctuary for Twitter users is).

That's perfectly fine, but in my experience, tech people tend to design a "world" for their needs, unintentionally excluding "non-tech people".

In my opinion, technology and science should serve all people and that developers and scientists have some responsibility for it.
Please don't get me wrong here, this is not meant to be a moral appeal, let alone a personal criticism of anyone associated with Fediverse.

In fact, I'm not at all altruistic when I talk about any kind of responsibility. Because offering my contacts who still use commercial networks today an adequate alternative in the Fediverse is my contribution to a Fediverse that meets my needs.
