I don’t agree with that framing, filtering out a certain class of txns (spam) isn’t censorship. Censorship is filtering out individual txns based on individual characteristics. Filters have been around forever, they’ve been working just fine. The busy body dumbfucks at core should have left things alone. If they wanted to tinker with fun little open source projects they should have found something else and left my money alone.

Filtering out a certain class of transactions isn't censorship (agreed), but it does resemble ad blocker behavior which is a form of centralization. In ad blockers, they all query a centralized list, or have trended to do so. Gov can put pressure on anything that is centralized. Yes filters work. That's the problem and solution unfortunately. Hence tradeoff between censorship resistance and decentralization.
