Ethereum's Credible Neutrality

A lot of concerns about attacks to Ethereum's credible neutrality emerged when, oh, fact specifically decided to sanction smart contracts associated with tornado cash. And that just raised a lot of questions around. Are our systems robust against this kind of censorship like if a group of entities decided to censor transactions? Ultimately, you want something like Etherum to be oblivious to the nature of the transaction. That should take place at higher layers of the system. This isn't a conversation around what is valid or not. This is a conversation around who gets to decide what is valid and not.
