Because a big “Join our community discord server!” on the game’s title screen isn’t enough apparently. They have to put a flashy animated GIF at the top of every update notification, change the name of the game’s Steam forum to “Join Our Discord!”, and even reply to posts in the Steam forum saying “You should join our discord so we can chat about it!” as if a forum isn’t a good place to chat about the thing that’s already being discussed.
Bitch please, if I wanted to be in the hell that is Discord I’d already be there, you can stop asking.
It’s only trapped on Discord if one refuses to ever join Discord. Most people playing games use Discord, so that’s not a real issue for them.
Making things searchable, such as problems and solutions, is dependent on how well managed a community is; over the years I’ve had plenty of issues trying to find something on a forum simply because something like keywords, and tagging didn’t exist or wasn’t enforced, or bug reports were regelated to a single forum thread.
The same it is with Discord. If you’re smart you’ll create a “forum” channel for bug and issue reports and force users to use tags as a rule.
Funnily enough, I actually don’t dislike discord as a platform, I’ve even built servers that have grown to hundreds and thousands of users. I’m also well aware of the attempts discord has made at rectifying the issues I outlined. That being said, it is absolutely a walled-garden and whenever discord’s servers are taken offline, countless amounts of information will go with them. At least with forums or a lot of other platforms, people can easily archive the info, not so much with discord.
