Discourse is a clean open source forum software that is commonly used for application support and well suited for it.
Or if your a real die hard for the fediverse, you could set up a lemmy instance for application support. There’s even a phpBB frontend for an oldschool forum look and feel for it.
Usually everyday people don’t setup forums, that’s the responsibility of the application owner(s) or provider. In this case, the easy option is also the shitty option if measured by discoverability of the content.
By this do you mean official forums? If so I think this is kind of missing some of the independent forums for software (whether games or media players or the like) or other media, which some sorta-everyday people set up in the past. Many have migrated to Discord not only because it’s easy but, I think, because it’s simply more cost-effective.
Forums don’t seem to be cheap. Discourse’s own managed hosting goes for $50 a month, from one of their partners it’s $20, and looks like somewhere in-between if you try to spin it up yourself (e.g. Digital Ocean droplet runs $4 a month, then add in domain, and mail-provider (~$20-35)). Looking at that, it’s little wonder so many either opt for official forums, unofficial subreddits, Lemmy/Kbin communities, or Discord servers instead now.
Maybe if I dug around some more I could find some options for managed hosting (which makes more sense for regular people, I think, to deal with technical maintenance) for Discourse or the like that are cheaper, but I can’t imagine one may find much that beats free. Unless there is something, unfortunately I guess we’re kind of stuck with the situation as-is barring some pleasant exceptions.
