The problem with @b0rk posts is that she describes how things are in the real world, not how they are in the vendor speech :-) Here her experience with Mastodon (you will probably disagree with at least one point): https://jvns.ca/blog/2023/08/11/some-notes-on-mastodon/
@bortzmeyer @b0rk It's indeed a very good summary and it's inline with my experience of running a personal server.
Another issue is the limitation of the post size -> https://github.com/mastodon/mastodon/issues/12265 which is a driving a lot users to use forks like Glitch soc.
