I'm already coming across more and more communities who say "For more information/to download the example files/to see our FAQ just join our Discord!", which is an immediate turnoff. I'm not going to "join a discord" just to see an FAQ or download some prerelease build or something else.

Now even entire communities are going to move onto Discord and become completely unreachable for people like me who don't want to "join the community" just to read one post that one person wrote one time.
