I'm genuinely happy someone shut down this thread immediately. It actually gives me hope now.
I've seen at least a few FOSS projects using Discord for support due to the fact it's practically monopolised the "mid-teen Internet culture" IM client choice and they think it means they can get more people in who will actually contribute.
Even if I use Discord sometimes, given more or less a reasonable choice I'd dump it as soon as I could do so, it's been abusing its monopoly since they gained it (the "cub" incident for instance, which everyone around me thought I was being a lunatic when I predicted such things happening since early 2017, and when they happened... lol - same with me predicting about Discord not really doing anything for free users since Nitro existed)
Communities on Discord seem to be about spamming and meme loving, to the extent they will not fix the light theme so people can bash it for the memes. Seriously? And don't even get me started on the amount of social outcasts seem to all gather around Discord/Twitter/Reddit in the same spaces...
The Discord lovers are way too loyal to see the problem with the platform which has been a great showcase of the post-2016 "commercialistic" apocalypse of the Internet that has rapidly increased (it started in 2012 but spiked up since 2016ish).
Rant over, and I needed to get that out honestly... IRC is far better suited for an open source community's needs, actually attracts relevant/quality discussion and has a comfortable feel to it that is impossible to get out of modern communities that seemingly rely on BigCorp's infrastructure to even have a reasoned purpose (in this case, Discord).
I don't mind "proprietary" IM for direct messaging or whatever but for whole communities to revolve around it's culture and the like will prove disastrous in some time (see: the ever growing anime NSFW lovers in their mid teens being told they're whatever by randoms)
