They are harder, but they eventually dominate the centralized systems. This is probably due to a combination of the O(n^2) value of the decentralized system dominating even the most valuable centralized system, and also the fact of centralization inevitably produces a whole bunch of people out to get the central player.
But I don't really know. This isn't an normative argument I'm making about what I think should be, it's an observation about history. Centralized email has given way to SMTP, for better and for worse. Centralized document systems gave way to gopher gave way to the web. Centralized newsgroups gave way to distributed forums. Centralized social media will eventually give way to a richer distributed ecosystem. I don't even know exactly how, but it will happen someday. It's just what happens. Eventually, too many people will be gunning for Facebook for them to be the monopoly.
(Probably the best counterexample is IM, which never properly federated. Arguably, this is because IM simply isn't that desirable. It's something people sorta kinda want, but not so much that it's actually monetizable, so possibly it's evidence in favor of the "success produces lots of people gunning for a piece of the pie" being the dominant factor. IM has never had anyone so successful (monetarily) that we had tons of people gunning for that space.)

Like Google, Amazon, Apple, Microsoft. All examples of big decentralized systems. Like the gradual consolidation of telecoms?
This is snarky, but only because I'm feeling sassy. Honest question, "Do decentralized systems actually win?" I hear this a lot as an axiom without any real evidence.
