Lua: The Little Language That Could
lua on its own right can be fun too! If you are looking for a project to contribute to, there's for instance the Prosody XMPP server that's written in it, and contributes to the betterment of internet by promoting federated protocols.
There's also the http://prosody.im/ XMPP server that's written in Lua, and it's very successful there. The other major XMPP server implementation is in Erlang and they are equally praised, so that should tell something about Lua's versatility.

A History of Lua
You can write largish standalone application in Lua and it is not always a poor choice - Prosody [1] first comes to mind. But qualities which make it a good embedded language make it less _attractive_ for other uses.
Lua has very simple syntax and small stdlib which allows its implementation to be very small - you can add Lua to your application and not increase its size significantly. But when the size is not a concern most programmers prefer languages with rich, powerful syntax lots of features and batteries-included stdlib (which is completely opposite of Lua).

Chat app to allow messaging between my daughter and I?
If you are really set on a LAN-only setup you could look at Prosody (combined with an Android app such as Conversations) which Snikket is based upon. It's not as "ready to go, out of the box" as Snikket and therefore requires a slightly higher skill level, but in exchange it is a lot more customizable and adaptable to different kinds of deployment scenarios.

Ask HN: What is your recommended stack for real time chat?
My choice, because it's the stack I know very well, would be Prosody ( https://prosody.im/ - I'm one of the devs) and a web client such as Converse.js ( https://conversejs.org/ ). XMPP is highly extensible, Prosody is highly modular, which make them a good foundation for building on top of.
That said, the right stack is generally the one that matches your requirements, and (if this isn't primarily a learning exercise) whatever you're most familiar with. The hardest part of building a Discord or Slack-like in 2022 is actually not the technical stuff. There are many comprehensive open-source products already out there that compete with these companies, such as Mattermost, RocketChat and Element.

Organizing OpenStreetMap Mapping Parties
What are you thinking of here? Synapse has supported purging room history since 2016: https://github.com/matrix-org/synapse/pull/911, and configurable data retention since 2019: https://github.com/matrix-org/synapse/pull/5815.
Meanwhile, Matrix has never needed the full room history to be synchronised - when a server joins a room, it typically only grabs the last 20 messages. (It does needs to grab all the key-value state about the room, although these days that happens gradually in the background).
If you're wondering why Matrix implementations are often greedy on disk space, it's because they typically cache the key-value state aggressively (storing a snapshot of it for the room on a regular basis). However, that's just an implementation quirk; folks could absolutely come up with fancier datastructures to store it more efficiently; it's just not got to the top of anyone's todo list yet - things like performance and UX are considered much more important than disk usage right now.

Non-profit Matrix.org Foundation seems to be moving funds to for-profit Element
Why not Matrix? Here's one reason: it has incredibly hard-to-debug edge cases, and plenty of bugs. One of my favourites is the one where people are kicked out of your room at random, which was reported a year ago[0]. It wasn't fixed, however, because the head of the Matrix foundation (Matthew) presumably didn't like the issue being posted on Twitter.
This is honestly really disappointing behaviour from a platform owner.

The Future of Synapse and Dendrite
> That doesn't make this situation any less bad to the rest of the community.
How is the community suffering here? Let's say Element adds a bunch of baller stuff to their versions over the next few months and then closes the source. Can't the community just fork the last AGPL version? You might say, "well then no one can take the AGPL fork and make their own closed-source business", but do you want them to? Even if you do, they still can with the existing Apache-licensed version, just like Element is doing right now.
You're arguing that Element will lose a lot of contributions, but TFA points out that despite being super open, the vast majority of contributions are still made by Element employees (which seems to be true [0]). It's not the case that Element is looking to monetize the (small) contributions of others, it is the case that others are looking to monetize the (huge) contributions of Element.
And besides, aren't the MSCs the core of Matrix? It's already super possible to build your own compliant client and server.
The situation is that Element needs money to keep developing the ecosystem. It would be cool if there were a big network of donors and contributions, but there isn't. You're essentially saying, "that's fine, go out of business then, and the community will keep developing the ecosystem", but that's not happening now, and it can still happen anyway with the Apache-licensed versions, which again people can still contribute to.
