I've always wondered wtf this term meant. This is a great article about these issues. And if you think it's a boring tech issue:
Bitcoin, as a system and community, largely seeks to maximize censorship resistance through decentralized transaction selection over any other goals. Sadly, today, bitcoin’s transaction selection is also highly centralized in the form of pools. Luckily, there’s no strong financial incentive for this, only historical technical reasons. While this allows us to massively re-decentralize bitcoin with only technical tweaks to the mining software stack, any financial disincentives to adopting such technology would absolutely destroy bitcoin’s long-term censorship resistance. So much so, that I’d argue that if we end up in the same place as ethereum is today, we should simply give up on bitcoin’s censorship resistance axiom as we simply will not achieve it in any reasonable way.
