Others have made great points already, but one thing I see mentioned is "I don't want to manage separate logins for all these forums". We need to remember that most people don't use password managers and don't like "logging in" to things. They see it as a hassle.

1 login to thousands of communities ? Easy win for Discord. If everyone made their own forum, these people would get login fatigue and just won't bother.
