Yeah, Occulus and Linux are not the best friends. There are some work arounds to make it somewhat work with SteamVR, but don’t expect too much.
My recommendation would be to look for a second hand Valve Index or HTC Vive if using it on Linux is your priority.
Or wait for the rumored new standalone headset from Valve, but that will probably not happen before end of 2025 if at all.
You can use https://webxdc.org/ apps with XMPP or Deltachat and shared grocery or task lists are a common use-case.
There are some clients that support the latest version of OMEMO, but yes, since the most popular ones do not, you end up using the older version most of the time. That said, the older version is not generally unsafe, it basically is the same as WhatsApp or Signal are using. The newer version is just somewhat better as it includes some lessons learned from earlier attempts.
E2ee is not everything, as most of the privacy sensitive metadata can still be collected. Sure it is nice to have, but even more important is that you can chose a trustworthy server operator or run your own. XMPP allows doing that, but it has some weaknesses with client implementations and so on.
I am a bit biased and would say all in all XMPP is probably the best option right now, but it depends on your specific priorities. It certainly has some rough edges though.
CoreCtrl might also work.
There is https://hypersomnia.xyz/ but it is 2D top down. Pretty tactical though.

No, if your system can’t support 3rd party clients properly, it is inherently insecure, especially in an e2ee context where you supposedly don’t have to trust the server/vendor. If a system claims to be e2ee, but tightly controls both clients and servers (for example WhatsApp), that means they can rug-pull that e2ee at any point in time and even selectively target people with custom updates to break that e2ee for them only. The only way to realistically protect yourself from that is using a 3rd party client (and yes, I know, in case of Signal also theoretically reviewing every code change and using reproducible builds, but that’s not very realistic).
Now admittedly, Signal has started to be less hostile to 3rd party clients like Molly, so it’s not as bad anymore as it used to be.
Telegram’s encryption isn’t open source, so no one can verify it’s soundness or risks.
This is not true, it is available in the open-source Telegram clients.
What you probably mean is that it is using an unusual and not well studied encryption algorithm. This means you need to be a real cryptography expert to spot flaws in it.
Telegram justifies this with a bit of FUD about well known encryption algorithm being NSA sponsored etc, but when cryptography experts did look at Telegram’s homegrown algorithm they were less than impressed.
There is a channel search engine, but yes for now XMPP is more of an alternative to Whatsapp or Signal for 1:1 communication or small group-chats. If you are looking for public channels the best is to join IRC channels via the very nice Biboumi gateway for XMPP.
There is an active project to enable MLS on XMPP right now, funded by Nlnet. Not many details yet, but from the little that is known it sounds quite promising.
After ignoring it because Epic sucks, I recently realised that https://heroicgameslauncher.com/ is a really nice GOG client as well.
Taler is not centralised. I think you are thinking of CBDC?
Taler could be described as semi-centralized at best. You are free to chose your exchange and you can easily use multiple the same time. It really isn’t that different to crypto-currencies in that regard if you consider the need of fiat exchanges for real world use there as well.
SimpleX is not suitable for larger group chats.
XMPP has a few quite popular privacy related public channels: https://search.jabber.network/search?q=privacy
(For those unaware: xmpp participant counts are actively connected users, not like Matrix or Discord that counts who ever joined the room years ago and never came back).
