What is really happening is that people are looking for documentation or support, seeing that the forum, the IRC and the Matrix are dead, that the only other thing is discord, and give up. Minus some fraction who already use it for other purposes (gaming, probably) and don't mind using it.
But from your perspective, it looks like everybody is joining discord and liking it, because all of the other people just give up. It's only a very particular demographic that uses discord. Most likely (I might be wrong, but this is what I guess) very young, male, gamer, european descendent, and from a relatively wealthy western country. That's a very small part of humanity.
If you as the maintainer go and use the forums, and maybe announce this in discord, the users will follow.
Like a survivorship bias?
Ooh! I'm surprised that somebody made the same conclusion, but from a different perspective.
I'm a member of a Discord that is the primary source of discussion and information about a piece of hardware, including technical & usage tips, firmware announcements, etc. It's a terrible way to track this stuff.
That said, the only other forums that have decent communities around it are Reddit, Facebook, and Elektronauts - none of which are even close to as active, but in which many of us will post important info & tips to get the news out. Over 3 years into the project (which is not open source) it would be ridiculous to try shifting the whole community to a new platform. We're kinda stuck.
Luckily the community as a whole seems to realise this, so we happily answer noob questions over and over and provide links to the appropriate resources, discussions, and pinned posts without snark or judgement. We've all been there. It's the nature of the beast, it's not efficient, and it's not the end of the world.
Finally, with the state of search engines in decline due to monetisation, encroachment of AI bloat, and general enshittification, it's a matter of time before very little real information will be easily searchable. Insular communities who decide to withdraw and do everything their own, better way will likely become the norm. The internet needs a reset anyway.
We have been using the forums. It's been announced in Discord, we have a webhook that posts in our main Discord channel every time there's a post in our main forum section. Every announcement goes to both the forums and the Discord, and the Discord announcements link to the forum posts.
We are using the forums. Our forums are still dead.
