That's a '51% attack' isn't it, could it be that easy for the BTC network to move from censorship resistant to censorship, because that's what it means if what you said above happens. I don't know the total hashrate controlled by censoring mining pools, but i think individual miners would withdraw from censoring mining pools if it ever gets to this point, that would surely reduce the hashrate they control.
Yes that’s purely a 51% attack (something we thought could take ages or high computational power to make it happen >: ). The two mining pools which are been linked to be censoring transactions is the F2Pool and Mara with both having a combined hash rate of 15%, so just as you said if the individual miners actually leave either of the pools and join the other pools that do not censor transactions then it will weaken thr hashrate of the pools and could take them out of the market. But the question remains will they leave and join others? Then the concern again is what if the government is able to get other big pools like Foundry ( which is US based mining pool ) and Antpool into their side, then the whole decentralization advantage that bitcoin possess will be gone. Something we have all thought will never happen, but due to maybe greed of some pools it almost right before us
