polyjuice_server VS sucks

There are a few other server implementations (polyjuice in Elixir https://gitlab.com/polyjuice/polyjuice_server; https://github.com/clecat/ocaml-matrix in OCaml; the abandoned mxhsd in Java) - but the most stable ones alternatives to Synapse right now are Dendrite (Go) and Conduit (Rust).

Matrix's API surface is big, and servers deliberately handle all the heavy lifting in order to make clients trivial to write, so writing servers is not trivial. But Dendrite & Conduit are both very usable and making good progress right now.

And yes, the APIs are all standardised (while also constantly evolving) as per https://spec.matrix.org :)

This is correct, and it's why most open-source software will never have much in the way of users:

> They're written from the perspective of the developers

And I get it. A few years back I had an open-source project [1] get users and it was terrible. What had previously been a fun technical exercise became a pain in the ass that felt a lot like actual work. I was relieved when my hardware broke and I had an excuse to archive the project.

But that does create a huge gap that mostly gets filled by commercial interests.

It seems like you haven't quite got the concept of open source. If everybody consumes and nobody contributes, how long will that last?

A while back I bought a cheap robot vacuum. Their scheduling feature didn't meet my needs, so I reverse-engineered the protocol and open-sourced a cron-friendly CLI tool and a library so people could do other things with it: https://github.com/wpietri/sucks

Honestly, this was a mistake on my part. It was a demanding audience of home-automation hobbyists mostly without programming skills. The company was thoroughly unhelpful. When my vacuum finally broke, I was relieved, as I had a good excuse for trying to hand off the project. Nobody stepped up, so I shut it down. I just ran out of interest in doing free work to support a company worth billions.

I really admire the community spirit of open source But it's not sustainable if companies making their money off it keep depending on the niceness and generosity of others without giving back enough to keep them happy, healthy, productive people.

I reverse-engineered the comms for my cheap Ecovacs robot vacuum and was surprised to discover that, like some angsty teen, it spent all day hanging out in an XMPP chatroom waiting for somebody to talk to it: https://github.com/wpietri/sucks/blob/master/developing.md
