It makes sense, but it's more than a little depressing and I would have thought the features wouldn't really be much of an issue for someone who chose that platform. Someone on Twitter might be aware that Reddit exists and how it works, but they're still not very likely to uproot themselves from a platform they know and use just for that (current events notwithstanding).

Can I ask what kind of service Hubzilla is, that puts it above the other options? Especially for nerds? I've heard the name maybe three times now, but I know nothing else. Is it just the fact that they're not tied down?
