I know, but it's still true in a sense that there's countless of individual entities mining around the globe. Mining operations are not centralized at all!

I'm not saying that everything's perfect and I believe we should focus on to talk about mining pool centralization or ASIC manufacturer centralization, but those are very different topics.

 

 Yes, but as long as the control over the next block contents is centralized, it doesn't help much. The operation is not centralized, but the final result that they bring (new block) is determined by an obscure few.
