Looks like Bitcoin Cash set a precedent, and now anyone with sufficient resources will split off on their own chain. I'm not sure what the long-term implications are, but I wouldn't say the communities/users are splitting away.

Many bitcoiners such as myself are still hodling their BCH and even use it occasionally. So the way I see it: with every split, some portion of the community will use the new chain and some won't.

So maybe it's a net gain for the crypto ecosystem overall as miners have more choices regarding which chain they want to mine, and users get to decide which chain is best suited for them. Competition is good, no?
