Does Mike Hearn act like he trying to weaken Bitcoin on purpose or does he do it naturally?
THIS is the big question. This is what we want to figure out. Assuming motives is equally as silly as assuming that the most advanced malicious and sophisticated attackers are sitting idly by while decentralization undoes their millennia-old process of consolidation of centralized power structures.
I don't think there's anything wrong with the latter assumption. Evidence suggests that the incumbents you are referring to almost certainly gamed the decentralisation trend as a scenario at least 20 years ago, if not further back.
