As long as the alternative is not another chat app that is not indexable by search engines. Forums fill the role pretty well, I don't understand why devs would use Discord in the first place.

There is stoat.chat (formerly Revolt). But you wont find much help on Lemmy or Mastodon. A lot of people on the fediverse have an aversion to Discord because when they try it, they have difficulty with it like a senior citizen with a smartphone. Even though Matrix and Discord arent similar, people on the fediverse will still try to recommend you Matrix, because they think Discord is just another messenger and not like having a forum, teamspeak, jitsi and other stuff in one program. And even if you explain it like that, they will be like "but then you can just use a forum, matrix, jitsi and a screenshare program separately" or something like that.

Open source community always loses to capitalists, because people won't do the work unless there's money involved. Otherwise there would be open source alternatives that are better and more popular. What incentive do smart programmers have to help the open source community when they're better off earning 180k+ per year programming for the financial sector? Especially in this ever increasingly oppressive economy. I'm sorry but unless leftists are donating billions to the open source community, it's idealistic at best to depend on them.
