Reddit has a large enough userbase that duplicate communities can each reach a sustainable size without interfering. The fediverse userbase isn't large enough to sustain even a single community for some topics, let alone duplicates. I'm in plenty of communities where there are lots of low value posts that would normally be consolidated into a single stickied post for the community but there isn't a large enough userbase to make a stickied post worthwhile despite there being multiple communities for that topic.

Also, reddit is a centralized system. A decentralized system is going to have problems that a centralized one doesn't

Any examples of those? What prevents those communities from merging?

I saw one recently in a linux community where a user complained about multiple "I ditched Windows" posts. I've seen requests for stickies in some gardening communities.

I assume nothing actively prevents the communities from merging other than the mods being comfortable running their communities. But they shouldn't have to merge. We can have solutions that enable multiple communities to exist while also preventing rampant crossposting and post duplication.

That's something that the moderators need to take action on, isn't it? Don't get me wrong, unmoderated communities is a whole issue on its own, but it doesn't seem linked to the community separation.

They don't have to, they can. But them being unwilling to merge similar communities seems strange, except if they can't agree on instance due to the instance politics.
