I think there is some incompatibility in that regard and the experience wouldn’t be good anyways.

This seems like something that would really benefit from better language support. I saw the translations folder in the repo, but you should probably get it linked up to a Weblate instance or similar and have people start contribute different languages asap.

Collabora Office works independent of Nextcloud. It can be nicely integrated into the lightweight https://www.filestash.app/ frontend for example.

I recently ended up replacing OnlyOffice with Collabora Office (Libreoffice based). While architecturally less efficient that OnlyOffice in theory, for my usecase where I rarely check some documents in Filestash it actually ended up using less server resources when idle than OnlyOffice (to my surprise).

UI wise they is no big difference IMHO, but docx etc. compatibility is slightly worse.

Dokuwiki has a well working WYSIWYG editor these days: https://www.dokuwiki.org/plugin:prosemirror

Mediawiki is a pain yes. I personally like Dokuwiki (see it in action here: https://wiki.slrpnk.net/ ) and Bookstack is also not bad (see it in action here: https://wiki.f-hub.org/ ), but it is a bit restrictive in regards to structure and access rights for other users.

They (Element / New Vector) got a major early investment in 2018 from Status, a cryptocurrency/web3 company, and later in 2021 an even bigger one in relation to Protocol Labs, who peddle their own cryptocurrency.

XMPP obviously. Have a look at https://joinjabber.org/

This is a fundamental issue of the Matrix protocol, yes. For regular small scale use it doesn’t matter so much, and the state history gets reset every time you do a room upgrade, which is another annoying “feature” of Matrix, but it eases the fundamental problem a bit.

But IMHO the Matrix protocol is a child of the Bitcoin hype era and is built on a similar data-structure that is inherently impossible to scale and the developers of Matrix should have realized that early on. Their bosses back then actually did, but they spun it off as a separate company and got some crypto-currency investments so the can was kicked down the road and here we are…

Nice ones 👍

https://kanboard.org/ is easy to run and works well.

Ghost in the machine 🤷

Impossible to tell and it sometimes happens.

There is a better, community maintained fork now: https://github.com/matterbridge-org/matterbridge

https://hypersomnia.io/ can be played in the browser and probably also selfhosted.

The XMPP channel search has a few channels that are not assorted geekery, but yeah most of it is.

Yeah, but you (or someone in a similar situation) will have to take them to court for the legal situation to be clarified. Just putting another license on the code will not stop them.

The problem is that the AI companies claim they are just “reading” the code to let their AI models learn from it, thus licenses / copyright doesn’t apply in their interpretation of the situation.

It supports Webpush, so if you use a browser for the PWA that support that you should be getting notifications. In my experience it isn’t quite as reliable as a native Android app though, but nothing really stops you to have both on your phone connecting to the same account.

You could also look into hosting a distributed Garage cluster for S3 compatible media storage with a few other people. Most fediverse software including Lemmy is compatible with that for image storage etc.

Snikket is definitly not harder to set up than Synapse or Condinuwuity, the difference is mainly that Matrix is based on standard web technology, so if you have some knowledge in that already, XMPP can feel a bit alien since it is an actual protocol different from http(s).
