Sad to see this eating up and killing off FluxBB. Seems like we're slowly but surely running out of basic, universal, no-nonsense forum software in favour of a move to Twitter/Facebook-timelines or Stack Overflow-style layouts, none of which are great mediums for organised discussion.
I would argue however that both Xenforo and phpBB are ridiculously bloated and should hardly be called basic. phpBB more so than Xenforo obviously. None of them offer the far more robust approach of FluxBB.
Thankfully, as FluxBB is opensource, it can be forked and saved from this development direction.
That was danneu's point - that any forum that actually implements most of what people will want out of it (just to start with - separate subforums/categories, user permissions, tags, thread and user following, local and email alerts, broad formatting options, media embeds, per-user display settings, etc etc...) is going to be well beyond "basic" just to get a userbase in the first place.
