Discord, the phenomenally popular proprietary chat platform, is now verified on Flathub. For years, a Discord Flatpak app has been available on Flathub
I personally wouldn't touch Discord with a 10 foot pole but figured any privacy-focused people who use it may want to know this.
It does seem like they hired someone to update their electron base so, presumably yes (you can see activity from a discord employee in their electron fork on GitHub)
Wut? Matrix is buzzing in tech circles. I can admit that it's not very popular outside of tech and Foss, but these are the contexts we're discussing here.
As a FOSS project maintainer, I provide a bridge between Discord and Matrix to give people the choice. Not everything he is comfortable with federated social media yet, and the Matrix federation specifically is not very stable.
I didn't make the reason for my request very clear. We need discussions to be archived and searchable from the internet. While Matrix is better than Discord when it comes to openness, it isn't much better in terms of searchability. Even the old Google groups were better. I would suggest something like Discourse (the forum).
Matrix is one option, if you just want a chatroom, similar to IRC. An online forum, like Discourse (not discord) is even better, since it creates a searchable history of past discussions. That way, most users who face any issue with your software can solve it themselves based on past discussions.
