Reddit, long one of the most exciting spaces for informed, topical conversations, is shedding users as it implements unpopular, Muskian policies in hopes of generating much-needed revenue. Some subreddits are migrating to Discord, where their conversations won’t overlap with thousands of other topics on Reddit, but where they have full control over their chosen rules of the road.

I feel the author missed the chance to mention fediverse. I think fediverse helps bridge in a non-trivial way the concern that smaller spaces lead to isolation. Fediverse allows small instances to interact with others (big or small). It is not magical answer to the problems raised but small is not necessarily bad and in many ways, it helps us reduce centralization while maintaining communication.
