Yeah, exactly this. Many of the communities on platforms like Reddit simply cannot co-exist, and having independent forums for them meant they could operate peacefully without those who dislike the fundamental premise of the community worrying or complaining about their existence.

You could probably even compare social media sites to schools or prisons really. Tons of people with different, wildly incompatible viewpoints or philosophies stuck in a place they don't really care for.
