Discord is a complementary product. There are several servers that have both a Mastodon and a Discord. Mastodon's features fill in gaps in information organization that Discord hasn't addressed, with one of the biggest being that by federating, it allows a community to go un-siloed and broadcast its output to others. Discord, on the other hand, is a superior method of onboarding among many demographics, if only because it has more inertia in that role and reduces their community onboarding to "add a new Discord". If they join a Discord and a community member says "we also have a Mastodon", that is their probable onboarding to Mastodon - not the server browser. Discord also acts as a backup for the technology, a secondary point of contact.
