I was referring to centralization more in the sense of concentration of effort and logic. I hate the word "consolidation" in this context.

Think of how science works. Lots of people focus deeply on specific topics and try to figure it out, model it and theorize the shit out of it until it's stable or abandoned to some obscure library that few look up. There are new topics, new domains, yes, but there's only one reality. Scientists don't just branch off into a "new reality" to research and reinvent science from scratch.

Wikipedia reflects that both methodologically and topically, with collective efforts to cover single topics well.

The power, maybe. Maybe our efforts should be collective, though; one wiki maintained by many is probably better than a lotta wikis maintained individually.

Unless you're doing a joke, in which case haha yeah capitalists can centralize deez
