Just because there are less pools than there are pure economic actors doesn't mean that the group as a whole has more power, it's just that it's less distributed because not enough people have their solar bitaxe yet (hyperbole, but for a reason - block template centralization is an issue.)

See pool share - it's under 2% and it looks like the peaks correlate with people renting off nicehash. I'd be totes happy if Ocean has 10% of the blocks, even if they won't mine coinjoins or p2a. Diversity is good.
