Except that Bitcoin miners have tried and failed to exercise any such power because it doesn’t exist. The most successful attack was creating a short-lived arbitrage opportunity between the massively pumped Bitcoin Cash and regular Bitcoin, which was able to slow down Bitcoin blocks as miners swapped chains until Bitcoin Cash backers either ran out of cash or dumped. All you had to do to not suffer from the attack was to just not do anything related to Bitcoin Cash. It was ultimately about extending the advantage of “ASIC Boost” miners by delaying a patch. The opportunity for miners to collude is completely offset by the fact that if they try to leverage their equipment somehow to delay or otherwise impact the main chain, you can just choose to mine instead to make better profits. Thus far there hasn’t been a single effective counter-play for miners that isn’t just “mine more Bitcoins and thus further secure the network” that isn’t just day trading with extra steps. Also who are these centralized miners anymore? Pools are centralized, but I’m a nobody who can mine profitably with very little capital involved. I can submit whatever block template I want. I haven’t been invited to any meetings.
